INTRODUCTION SUMMARY STATEMENT Public Service Company of Colorado (Public Service or PSC) submits this Special Review Permit application pursuant to Colorado Revised Statute 30-28-110 and Section 25 of the Weld County Zoning Ordinance, for three construction projects associated with the decommissioned Fort St.Vrain(FSV)electric generating facility. The three projects include construction activities at FSV necessary to convert the facility to a gas fired combined cycle steam plant, construction of a small photovoltaic (solar) demonstration project on FSV lands, and construction of natural gas pipelines to provide natural gas to the new FSV gas fired combined cycle steam plant site (see Figure 1 - Vicinity Map). This application will include two "DETAILED REPORTS." The first provides information on the construction activities proposed to occur on existing FSV lands and the second addresses construction of the natural gas pipelines which will provide a natural gas source to FSV and reinforce the PSC natural gas system located along the front range of Colorado. Section III. "DETAILED REPORT - NATURAL GAS PIPELINE" also contains information regarding the pipeline route selection process, project impacts, mitigation measures, etc. (see Table of Contents). STATEMENT OF NEED PSC routinely evaluates its electric generation and transmission system to ensure reliable and economical electric service to its customers. The demand for electricity, termed "load", is derived from the demand for goods and services that use electricity. Periods of slow economic growth generally result in less than average growth in electric demand. Periods of high economic growth generally result in above average growth in electric demand. It is because of this relationship that PSC considers economic factors in forecasting future electric demand. Economic growth in the PSC service territory continues to surpass that of the national average and is predicted to continue doing so in the near future. As a whole, the PSC service territory economy is estimated to expand at approximately 2% annually. This continued economic growth is the primary determinant of future increases in electricity energy sales and peak demand. Public Service intends to repower FSV, based upon a "preferred plan" that evolved from an integrated resource planning process. The Integrated Resource Plan (IRP) is an extensive document which was approved by the Public Utilities Commission (PUC) and followed an extensive set of planning rules developed by the PUC. The plan identifies projected electric load requirements and provides solutions to meet those requirements through the"Preferred Plan". Utilities in 20 other states have similar processes to help plan for the future electric needs of their customers. The IRP development process is also consistent with federal regulations such as the "National Energy Policy Act of 1992" and the "Public Utility Regulatory Policies Act of 1978" as amended. 1 vn > " 1 z �� , 8a n LI- w a) r..-1.._.._.._ _ _ o— I 0a � Cf)U ?

Public hearings were held in April of 1994 before the PUC. PSC presented extensive testimony including the recommendation that FSV be repowered as a gas fired combined cycle steam plant and that PSC construct a photovoltaic demonstration project to gather data for future applications. Public Service's "preferred plan" indicated that repowering FSV utilizing natural gas was desirable because Public Service could then reuse existing FSV assets. The existing steam turbine generator, condenser and many auxiliary facilities will be utilized to produce electricity for Public Service customer needs into the next century. The PUC agreed that Public Service's proposal to repower the idle FSV generation station as a gas-fired combined cycle steam plant was critical to PSC's meeting future projected electric generation load requirements (Decision Number C94-743). In June of 1994 the PUC granted a Certificate of Public Convenience and Necessity(Decision Number C94-862) for this project. The PUC has also approved the construction of a photovoltaic demonstration project which PSC proposes to construct on FSV lands. Construction of a Photovoltaic Demonstration Project will allow PSC to gain information on solar technology and its potential applicability as an electric generation source. PSC is proposing to construct a 20-50 kilowatt (kW) photovoltaic system on a 225 feet x 300 feet parcel of vacant FSV land (See Figure 1-Vicinity Map for location). Electricity produced from this facility will be relatively small but will provide important information on the applicability of solar power as a future generation source. PROJECT LOCATION The Fort St. Vrain (FSV) site is located approximately 3 miles northwest of Platteville, Colorado in western Weld County. PSC owns approximately 2,800 acres around FSV consisting of the industrially zoned plant site, cropland, pastureland and stream bottomland. Approximately 2,244 of the 2,800 acres surround the immediate FSV plant site. The property is near the confluence of the South Platte River and St. Vrain Creek. PSC proposes to install two new Combustion Turbine Generators (CTGs), two associated Heat Recovery Steam Generators (HRSGs) and appurtenant facilities associated with these generators on the existing industrially zoned FSV plant site. PSC also proposes to construct the photovoltaic demonstration project on approximately 1.6 acres just northeast of the FSV plant site on FSV lands. Natural gas transmission pipelines will also be constructed to provide natural gas for the FSV Steam Plant and to reinforce PSC's natural gas system along the front range. A description of the pipeline locations is included in Section III. "DETAILED REPORT - NATURAL GAS PIPELINE" of this application. 3 PHYSICAL DESCRIPTION FSV Steam Plant Site FSV was originally constructed as a High Temperature Gas Cooled Reactor utilizing a uranium-thorium fuel cycle. Helium was the primary coolant used to produce the super heated steam which turned the steam turbine generator to produce electricity. PSC is currently decommissioning the nuclear generating facility but several existing components will be utilized in the repowering effort. Decommissioning will be complete in early 1996. The actual plant site area occupies less than 5% of the total PSC land at FSV. PSC proposes to install the new combustion turbines and associated equipment on the current plant site within the existing I-3 zoned area (indicated on Exhibit 2 - Boundary Survey of FSV). Most visible construction activities will occur within a relatively small area just east of the existing Main Turbine Building (see Exhibit 3 - Plant Layout Map). The proposed repowering effort will occur in three phases (Phases 1A, 1B, and 2) which will allow PSC to utilize existing power generation facilities including the steam turbine generator, cooling water system, condensate and feedwater system,water treatment systems and substation. Several existing buildings will be removed before new equipment installation can occur including the Construction Workshop, Pole Barn Storage Building, QA/QC Lab and Snubber Shop. Exhibit 4 - Basic FSV Site Plan, identifies the area where the two CTGs and HRSGs will be located. The tallest structures associated with the new construction will be two 175 feet tall HRSG exhaust stacks, both which are approximately 6 feet taller than the existing building just west of this proposed construction. Repowering the FSV plant is scheduled to occur in phases over a 5 year period. This phased-in construction approach allows PSC to add generating capacity in increments corresponding to or with actual customer load growth requirements. This proposed phased approach will result in a total net plant output of 471 megawatts (MW). This application is for Phases 1A-2 shown below. Construction is proposed to occur in the following sequence, but may vary slightly depending upon future load growth changes. Phase 1A 1996 - Install one simple cycle Combustion Turbine Generator (CTG) for a net plant output of 130 MW. Construct approximately 22 miles of gas transmission line through Weld County to ensure an adequate source of natural gas at FSV. Phase 1B 1998 - Convert the simple cycle CTG to a combined cycle plant by installing one supplementary fired Heat Recovery Steam Generator (HRSG) and the corresponding main steam, reheat steam, condensate, and feedwater piping systems to repower the existing steam turbine, for a total net plant output of 232 MW. 4 • • Phase 2 1999 - Install a second CTG and supplementary fired HRSG unit for a total net plant output of 471 MW. An additional electric transmission line will be required for Phase 2. PSC will submit a separate Special Review Permit application for this proposed new electric transmission line at a later date. Photovoltaic Demonstration Project The photovoltaic demonstration project will be constructed approximately mile northeast of the FSV Steam Plant Site on a vacant parcel of PSC owned land approximately 225' x 300' (see Exhibit 5). Photovoltaic arrays will be installed on the level site within a fenced area. These panels or photovoltaic arrays are constructed from photovoltaic modules that produce approximately 60 watts each. The photovoltaic arrays will be either "single-axis tracking" (to track the sun), or "fixed flat plate" at an approximately 20° angle. Figure 2 illustrates a typical design of a 400 kW installation utilizing "fixed flat plate" arrays located in California. The proposed project at FSV will be similar in appearance to this typical design but will occupy a much smaller area since it will only produce 20-50 kW. A weatherproof enclosure will also be constructed. The enclosure will contain a power conditioning unit to convert the power from DC to AC and step the power up to 13.2kV. Also included in this enclosure, or possibly a separate enclosure, will be protection equipment and a data acquisition system to monitor the project's electric production, etc. The components in this project will not exceed 25 feet in height. The system will have a 20 year design life. Transmission Line Requirements The new generating capacity from FSV will supply electricity through PSC's existing transmission system via the 115/230kV substation at the plant site. However prior to completion of Phase 2 construction, a new electric transmission line emanating from FSV south toward the metro area will be constructed to transmit Phase 2 electricity into PSC's electric transmission network. A separate Special Review Permit application will be prepared for this new transmission line. Mitigation Impacts associated with construction of the FSV steam plant and the photovoltaic demonstration project are expected to be minimal since new FSV construction activities are within an existing generation plant site and the photovoltaic demonstration project site is crop land within an I-3 zone district. Mitigation measures associated with the natural gas pipeline construction are described in Section III."DETAILED REPORT-NATURAL GAS PIPELINE." 5 I /ii. ` re?" 1 'e. lit 7/ ... ., • _... ., . • . i • \ . . ..., , _„ , . . .. , . .. , 4 6 t SI', '" i, ..,.ili 1:...,..,,, , . .., ie.:\t .../:,,>:' , \\ 1 i ••• / • I: , • . , {, ‘1„ • , • ..

The temporary work force will consist of construction workers at the FSV plant site and workers constructing the new natural gas pipeline system to FSV. The construction work force will be intermittently employed between mid-1995 until mid-1999. During peak construction periods, approximately 150 personnel will be involved in construction activities associated with the FSV steam plant site and approximately 100 workers will be utilized to construct the new natural gas transmission pipeline to the plant site. The temporary workforce will not require permanent on-site dwellings for housing. The non-local workforce will reside in area motels or other temporary housing such as rented apartments. Although not finalized at this time, the permanent FSV staff is anticipated to consist of approximately 30 personnel. Approximately 6 construction personnel will be required to construct the photovoltaic demonstration project. No additional permanent on site personnel will be required after project completion. WATER REQUIREMENT PSC owns extensive water rights which will be utilized at FSV. Repowering FSV to the 471 MW level with steam will require approximately 1,734 acre-feet of water/year. PSC will not acquire any additional water rights as a result of this project. Water will be diverted from the South Platte River and St. Vrain Creek. Domestic water is supplied from Platteville, Colorado. Existing water transport facilities including diversion structures and pumping stations will be utilized to transport water to steam plant facilities. FUEL REQUIREMENT Fuel for this project will be natural gas. The gas supply must be adequate to allow the Phase 1A CTG to be started and producing 130 MW of electrical power within 10 minutes. The natural gas requirement will be even greater with the construction of Phases 1B and 2. See Section III. DETAILED REPORT - NATURAL GAS PIPELINE" regarding pipeline design and capacity. Solar radiation from the sun is the source of fuel for the photovoltaic demonstration project. WASTE DISPOSAL Portable sanitary units will be provided while construction is in progress for the various activities identified in this application. All waste and remnant materials will be removed from construction sites and disposed in a proper manner. After construction of the gas pipeline and photovoltaic system, waste disposal will not be required since waste will not be generated. 7 At FSV, personnel are aware of the necessity to minimize waste generation during work activities, and to clean up the areas following completion of work. Empty containers are removed for disposal or storage, and any debris is placed in the appropriate containers (recycle bins, hazardous waste satellite accumulation areas, commercial waste bins, etc.). Trash collection is performed on a routine basis for most commercial trash, with removal of scrap or other special waste materials performed on an as-needed basis. Industrial wastes are collected, stored, and shipped in accordance with written procedures and per applicable regulations. Housekeeping status is monitored by Plant Management and Operations on a routine basis as part of their daily activities. Additionally, Plant Management performs monthly tours of specified areas for this very purpose. PSC oversees all contractor activities at the site. 8 II. DETAILED REPORT - FSV STEAM PLANT SITE & PHOTOVOLTAIC DEMONSTRATION PROJECT INTRODUCTION The preceding Section I. "INTRODUCTION," addressed pertinent aspects of the project as outlined in the Major Facilities of a Public Utility Use by Special Review Procedural Guide. In accordance with this procedural guide and section 25.7.2.4 of the Weld County Zoning Ordinance, this section of application presents a more in-depth discussion of certain topics addressed in the "INTRODUCTION," in addition to several new topics. PROJECT ALTERNATIVES Converting FSV to a gas fired combined cycle steam plant was only one option considered by PSC to help meet future electric load growth requirements. As discussed in the "STATEMENT OF NEED," PSC conducted an extensive planning process, as required by the Colorado Public Utilities Commission (PUC), to develop an Integrated Resource Plan (IRP). During the IRP process, a "preferred plan" evolved which PSC is proposing to implement several of the highest priority items, including the conversion at FSV and construction of the photovoltaic demonstration project. In developing this "preferred plan" PSC drew upon information gathered from over 18 months of work, including detailed analyses and modeling of the electric system, assessment of numerous proposals from both non-utility generators and neighboring electric utilities and discussions with outside parties representing a variety of public interests and concerns. The "preferred plan" utilizes a combination of existing energy resources and new energy resources in an appropriate balance to serve customers in a reliable, low cost manner, with minimal environmental impacts, flexibility, and the assurance of long term sustainability. Selected Generation Site Repowering FSV is an important component to meet PSC's future load growth. During the IRP process it became apparent that the utilization of existing FSV facilities allowed PSC to redevelop an economical generation source that could have flexibility through a phased construction program. These generation sources could also be brought on-line fairly quickly and have minimal impact to a site since an existing facility is in place. As previously stated, the PUC agreed that FSV is an appropriate site for PSC to develop this gas fired combined cycle steam plant and ensure future customers will have an additional source of reliable and economical electricity. 9 Photovoltaic Demonstration Project PSC, with the assistance of the National Renewable Energy Laboratory (NREL), selected FSV as a suitable site to gather data from the installation of a solar demonstration facility. Land is available and the close proximity to the front range/metro area allows for easy accessibility and monitoring of the photovoltaic system. This location will allow PSC to gather data on the actual performance of the system and to gain construction, operating and maintenance experience on a larger scale solar system. The project is also an important step in PSC's commitment to utilize renewable resources such as solar and wind power to generate electricity on a larger scale. PROJECT DESIGN FSV Steam Plant Site The conversion to natural gas at FSV will utilize a Combustion Turbine System to produce electricity. The function of the Combustion Turbine System is to produce thermal energy through the combustion of natural gas and to convert the thermal energy into mechanical energy required to drive a compressor and generator. The Combustion Turbine System consists of two Combustion Turbine Generators (CTGs), supporting systems such as the Heat Recovery Steam Generators (HRSGs), and associated auxiliary equipment. Atmospheric air is supplied to the combustion turbine through the inlet air filter and associated air inlet ductwork. The air is compressed in the compressor section of the combustion turbine, then exits through the compressor discharge casing to the combustion chambers. Fuel is supplied to the combustion chambers where it is mixed with the compressed air and the mixture is ignited and burned. The high temperature, pressurized gas produced by the compressor and combustion section expands through the turbine, driving the compressor and electric generator. When exiting the combustion turbine, the combustion gases are directed into the HRSG and exits the HRSG into the exhaust stack. The Heat Recovery Steam Generator System will provide for the transfer of heat from the exhaust gases of the combustion turbine to condensate, feedwater, and steam. This heat transfer will produce superheated steam at the pressures and temperature required for admission into the steam turbine through a series of pipes connected from the HRSGs to the steam turbine in the Main Turbine Building. See Figure 3 for a depiction of a simplified Combustion Turbine System with Heat Recovery Steam Generator System and how it will be integrated into the existing FSV plant. 10 0 Figure 3 0 W O U s > CI. .a Cr) = rr 411 lidw a) a N c • LC Cn a,co c � � ti) f � H CD CD a I 'ffl "i ' 11a. z � Q °' ❑ o- E y 0 Q -0? 7,7) L i lilt U y cri Cu C wr‘ r: O IIIIIII II0- `r 0 J o ins W a) c i_a -� ❑ _ w 11 iEO) n I. = CC r Y 0) y C t I l•- n 7) \ u / a--:- O a �0 L7 -44 - F-� Q 1 Cbully icivawa�ddng O 7L--Lk in `� C �� ■- = a / 8 CO N cu cu T .- n— c.: r E W Ca)a) I X N /O LU \-----------Th C---- ,-- •• r I—Ico Et uind icluawalddng 73 = o Ch n w Ca 3 E y m ` a y----'g 0,---- - (.0 2g E OII `u in Cu H h.- x V --/ '^ d ti O a c eis La O is \ •• J 0,) r_i _ 1 a, o co N " . a, ._ r = .... .., .-c_-, •__ 0 . a cc..

Phase lA consists of installing the first simple cycle CTG. Phase 1B consists of adding an HRSG and partial repowering of the existing steam turbine. Phase 2 consists of installation of the second CTG and HRSG (see FSV Site Plan). Additional work at the power plant site will include the refurbishment of the existing control room, modifications to steam condensing equipment, installation of piping from HRSGs to existing turbine building, installation of additional fire protection equipment, modifications to plant cooling water equipment, installation of a new distributed control system, new control and electrical equipment for protection and operation of the generating unit from the control room, construction of gas supply piping from the plant boundary, addition of equipment to plant substation,construction of additional fencing and temporary construction facilities. Removal of several obsolete buildings is scheduled to occur before the new construction begins including the removal of the existing Construction Workshop and Pole Barn Storage Building just east of the Main Turbine Building. Photovoltaic Demonstration Project The solar or photovoltaic(PV) demonstration project will consist of PV array structures and foundations to support the PV modules, an isolation/step-up transformer, and a power conditioning unit. See Figure 2 for an illustration of a typical PV array arrangement. Additional equipment shall include wiring, connectors, protective devices, grounding, junction boxes and enclosures, a data acquisition system and other items needed to construct a fully functional utility interactive PV system. The 20-50 kW produced will be tied into a 13.2kV electric distribution line that branches off to feed some of the northern buildings at FSV. The PV generated electricity can be used by anyone interconnected with the 13.2kV line and is not solely dedicated for use at FSV. The 1.6 acre site is part of an existing FSV farm plot located just northeast of plant facilities (see Exhibit 5 - Certified Boundary Survey of site). A 7 foot tall chainlink perimeter fence will surround the site and a gravel access road will be constructed just inside the fence around the entire installation. There will be no building at the site, however, a weatherproof enclosure(s) will be constructed to provide protection for the power conditioning unit and the data acquisition system. The photovoltaic installation will be either "single-axis tracking" or a "fixed flat plate" (at approximately a 20° angle) design. The configuration will be determined when the final designs are completed and evaluated by PSC. The make up of the cells is undetermined at this point. The PV modules will be either a blue or black film showing through glass. The equipment layout shall provide a minimum of 2 feet clear area above grade vertical access 12 • • for maintenance of equipment including weed control. The final layout will be designed by a contractor with PSC approval, however, no equipment will exceed 25 feet in height. The system will have a 20 year design life. PROJECT COST Public Service is mandated by the PUC to provide reliable and economical electricity to its customers. Extensive analysis indicates that repowering FSV as a gas fired steam plant is economical and flexible because of the phased approach to construction. Generation capacity can be added based on actual electric demand. Approximately $198,000,000 in 1993 dollars is budgeted to complete phases 1A, 1B and 2 to produce a total of 471 MW of generating capacity. Funding for the photovoltaic demonstration project will come from several sources. PSC is providing the site and approximately$151,000 for the installation. Additional funding may be obtained from the U.S. Department of Energy, the National Renewable Energy Laboratory or the Electric Power Research Institute. PSC hopes to obtain the data acquisition system and some monitoring equipment from PVUSA(Photovoltaics for Utility Scale Applications), an organization within which PSC is a member. Final engineering is not complete for this project so cost is not known at this time. PROJECT SCHEDULE Public Service has received approval from the PUC to repower FSV through Phases 1A, 1B and 2. Detailed engineering and design activities have begun to integrate the new facilities with the existing plant equipment. Construction activities associated with the Phase 1A CTG installation are expected to begin in April of 1995 and continue into mid-1996. Construction of the natural gas pipeline to FSV must also be complete by early 1996 in order for the CTG to begin testing and become operational (see III. "DETAIL REPORT - NATURAL GAS PIPELINE"). The Phase 1B HRSG construction is anticipated to begin in February of 1997 and continue into the spring of 1998. By late spring 1998 PSC plans to have 232 MW of electric generation capacity available to bring on line. Phase 2 construction is anticipated to begin in 1998 and be complete in the first half of 1999 increasing electric production to 471 MW. However, the phase 1B and 2 schedule may be accelerated or delayed slightly depending upon actual load requirements that develop in 1995 - 1997. This phased approach allows flexibility and provides PSC with the opportunity to construct generation facilities as needed, a major benefit of this project. Construction of the photovoltaic demonstration project is anticipated to occur in the spring or summer of 1995. PSC is working to finalize the actual design of this system. Actual installation of the equipment will take about one month. System testing will also take about one month before the project is fully operational. PSC hopes to have a fully operational system in place before the end of 1995. 13 • • EASEMENTS No new easements are anticipated for construction activities on existing FSV lands including Phases 1A, 1B and 2. Also, no easements will be required for the photovoltaic demonstration project since the site is also located on lands owned by PSC. Easement requirements associated with the natural gas pipeline construction are addressed in Section III of this application. PROJECT IMPACTS Agricultural Lands Construction on FSV lands associated with the repowering effort will not impact agricultural lands. The site is located within an existing I-3 zoning district. The photovoltaic project will be located on a 1.6 acre parcel of FSV land adjacent to the actual power plant site. PSC leases much of the FSV land around the plant site for agricultural use. Land around this 1.6 acre parcel could continue to be farmed. Also, the 1.6 acre photovoltaic demonstration project site is within the existing I-3 zoning district. Mineral Resources Conversion of the FSV generating station to a gas fired combined cycle steam plant and construction of the photovoltaic demonstration project will not impact mineral resources in the area. Wildlife Habitat Impacts to wildlife habitat will not be increased by the repowering construction effort or construction of the photovoltaic demonstration project at FSV. Historica4 Archaeological and Scenic Resources No new impacts to historical or archaeological resources are anticipated with construction activities on FSV lands. If an unknown historical or archaeological resource is encountered during construction, PSC will immediately inform the proper state and federal agencies. Impacts to scenic resources in the area will be minimal since construction will occur within an existing I-3 zoning district where industrial uses currently exist. Two 175 foot tall exhaust stacks will be the tallest structures associated with the project (Phases 1B and 2). These exhaust stacks are approximately 6 feet higher than the existing decommissioned reactor building located just west of the new construction. 14 i • Visual Impact The I-3 zoned FSV plant site is not in an area of great visual exposure. The plant site is in a bottomland environment as created by the South Platte River and St.Vrain Creek. The plant site is surrounded by over 2000 acres of PSC owned land. This non-industrial land acts as a buffer and is characteristic of the surrounding rural/agricultural landscape of Weld County. Cottonwood trees in the bottomland provide additional visual buffering around the plant from county roads and highways, especially during the growing season months. Colorado State Highway 66 is the closest major thoroughfare utilized by the general public. This two-lane paved road is almost 3 miles from the FSV plant site. Interstate 25 is approximately 5.5 miles from the plant site and Highway 85 is almost 3 miles from the plant site. Platteville, Colorado is the closest community to the plant site. It also is approximately 3 miles from the site. Visual impacts from the photovoltaic project will also be minimal since the height of the equipment will not exceed 25 feet and the distance to areas of general public travel (main roads, etc.) is 3 miles or greater. Air and Water Pollution The major air pollutants that could occur after construction and operation of the Ft. St. Vrain combustion turbine generators are oxides of nitrogen (NO.), carbon monoxide (CO), Unburned hydrocarbons (UHC), sulfur dioxide (SO2), and carbon dioxide (CO2). In order to minimize NO, emissions, the Ft. St. Vrain CTGs will use the latest combustion control technology, dry low-NO. combustors. In the recent past, both water and steam injection has been required to meet the low emissions required for a new installation. Manufactures have now developed new dry low-NO, combustors that allow efficient combustion while minimizing NO. emissions. When either water and steam injection are used for NO. emissions, CO emission generally increase. The dry low-NO. burners allow the lower NO.without increasing CO significantly. UHC are comprised of volatile organic compounds (VOCs) and methane and result from incomplete combustion. These emissions are generally reported as equivalent methane (CH4). Ft. St. Vrain will use natural gas for all firing, thus, SO2 emissions will not exist on this unit. CO2 emissions occur with all fossil fuels, but due to the exclusive use of natural gas, CO2 emissions will be lower than other fuels. The estimated concentration of the three major air emissions at full load using dry low-NO. combustors vary depending on combustion turbine operation (simple or combined cycle) as shown below: NO. ppmvd corrected to 15% 02 18-25 CO ppmvd 4245 UHC ppmvw 7-22 15 • II Preliminary emissions modeling of the first two CTG units has shown no major impact to the local or the wider range area and preparation of a Prevention of Significant Deterioration(PSD)permit is in progress, as required by the State of Colorado. While only preliminary screening models have been completed to date, the PSD permit application will contain results from more detail modeling. For the PSD permit, we assume worse case condition and assume the turbines operate at full load 365 days per year. Our operating plan currently filed in the IRP with the PUC assumes a capacity factor during the first two years of 1-2% when the system will be operated as a simple cycle unit. In 1998 additional equipment will be added to allow heat recovery from the combustine turbine exhaust gas and the unit will be operated as a combined cycle unit which will increase the capacity factor efficiency and thus lowers the operating cost per unit of energy. The capacity factor will then increase to 30 to 50% in the later years. While the lower capacity factors are reasonable estimates, the PSD permit will be obtained with no capacity factor restrictions and will allow continuous full load operation. Table 1 below indicates the expected emissions for the worse case, ie; 100% capacity factor, and a more realist emission estimate based on the current IRP follows. This table shows all emissions in tons per year (tpy). These are all preliminary estimates based upon the anticipated CM manufacturer. All values assume an average temperature of 59°F.

Existing plant facilities will be utilized to condition and cool the water prior to discharge into the river system. In addition, no air or water pollution impacts are expected from construction of the photovoltaic demonstration project. 16 • • Impacts on Local Government Repowering FSV will have a significantly positive influence on the area's economy. The project will provide approximately 30 permanent jobs necessary to operate the plant. The tax base will increase as each phase is constructed. However, additional service related impacts to area special districts will be minimal since the existing plant site is only being modified operationally and police protection, fire protection, etc. already exists. A list of local governments and special districts associated with the projects are identified in section III. Transportation PSC will use existing area railroad systems and roadways to bring construction materials to the FSV area. Prior to shipping any of the heavy components, PSC personnel or contract representatives will conduct reconnaissance activities and evaluations of area roads and bridges to ensure structural loadings to these facilities are not exceeded. HAZARDS & EMERGENCY PROCEDURES No geologic or flood hazards exist at the FSV site. The existing plant site is stable geologically and not located within the 100 year or 500 year floodplain. PSC currently employs an Environmental and Occupational Health Coordinator at FSV to monitor plant activities. Extensive plans and contingencies address any imageable event that could occur. PSC conducts detailed preventative maintenance programs which include regular inspections of equipment and facilities to minimize hazards and ensure employee safety. A wide variety of FSV plans exist including the Emergency/Contingency Plan for Chemicals,Petroleum and Hazardous Waste and the Emergency Response Plan both which provide mechanisms to classify emergencies at FSV and to describe organizations and communications required to manage the emergency and outline the appropriate course of action. PSC provides area communities and Weld County with copies of the Emergency Response Plan and other appropriate plans regarding potential emergency situations that could arise at FSV. Three copies of the Emergency Response Plan have been submitted to Weld County personnel with this application. Chemicals such as oils, lubricants, paints, thinners, solvents, cleaning agents, sealants etc. used for operating plant equipment are stored in buildings throughout the plant in small quantities. Bulk quantities are only stored in buildings, tanks or rooms designed for those purposes. Secondary containers or spill control (e.g. catch sumps) are typically used to prevent loss of product in those areas. Natural gas will be the new fuel source at FSV for generating electricity. PSC considers "safety" as the highest priority at all of its facilities. An active safety program is in place to 17 • • educate and protect employees throughout the company and minimize any dangers that may exist. PSC designs and constructs its facilities to meet all applicable federal, state and local safety regulations. Access to the plant site by the general public is controlled at FSV. Development around the immediate plant site is restricted to PSC approved activities. PSC maintains the over 2200 acres that exist immediately around the FSV plant site and this acreage provides an effective buffer between plant activities and the general public. No major population exists in the immediate plant area. The closest community, Platteville, is approximately 3 miles away. Public Service Company strives to ensure that dangers or hazards created by construction associated with the repowering effort, construction of the photovoltaic demonstration project, or construction of the natural gas pipeline is minimized. MITIGATION Construction at the FSV plant will occur in an existing I-3 zoning district on currently utilized lands. Mitigation requirements at the plant site are expected to be minimal. As stated in the "INTRODUCTION" section of this application, mitigation requirements associated with the natural gas pipeline are discussed in Section III. "DETAILED REPORT - NATURAL GAS PIPELINE." COMPLIANCE WITH THE WELD COUNTY COMPREHENSIVE PLAN Construction on FSV lands associated with converting the FSV plant to a gas fired steam plant and construction of the photovoltaic demonstration project are consistent with the goals and objectives of the Weld County Comprehensive Plan. Three applicable goals from the Weld County Comprehensive Plan dated March 24, 1992 include: 1. Expand and diversify the industrial economic base. 2. Accommodate new industrial development within planned industrial areas. 3. Promote development that is appropriately located in relation to surrounding land uses, and that meets necessary environmental standards. Public Service Company of Colorado is proposing to expand upon and diversify an existing industrial facility by converting a decommissioned nuclear facility to a gas fired steam plant and by constructing a photovoltaic demonstration project. These proposed facilities are located within a planned and existing I-3 zoned district. These developments are compatible with surrounding land uses, especially since they are located at an existing facility and are being engineered and designed to meet local state and federal environmental standards. 18 • • PUBLIC MEETINGS/COMMUNICATION PSC has consistently communicated with the communities surrounding its former FSV nuclear generating plant for a number of years. However, because of the rapid pace established during the initial period following the decision to shutdown the nuclear generating station, PSC set forth a substantial effort to increase public awareness of decommissioning activities and to encourage public communication beginning in the late 1980's and continuing today. Specifically the company's effort has included a quarterly community newsletter and community information meetings, door-to-door surveys in 1988 and frequent participation in area community activities. Additionally,PSC placed information articles in the Platteville Herald describing activities associated with FSV. Because the site was a nuclear facility, PSC annually mailed"Emergency Preparedness"information to residents living within a five- mile radius of the former nuclear plant until 1992. Until 1993, the newsletter was mailed quarterly to residents living within five miles of the plant as well as the town councils for the cities of Fort Lupton, Johnstown, Milliken, Platteville and Gilcrest. In addition, the "Fort St. Vrain Neighbors' Newsletter" has been mailed to the Weld County Commissioners. In 1993 and presently, the newsletter is mailed semi-annually to discuss events at FSV including the repowering effort. Community information meetings were offered quarterly beginning in 1988 through 1992. Beginning in 1993 as decommissioning continued to progress on schedule, information updates were offered and conducted as requested by the city councils of Fort Lupton, Johnstown, Milliken, Platteville and Gilcrest. The updates also have been presented to the Weld County Commissioners. The presentations provided progress reports on the decommissioning activities, and in January of this year, the town of Eaton requested and received a presentation on decommissioning and repowering. More meetings will be offered to the five city councils and commissioners later this year. As work progressed with the Independent Spent Fuel Storage Installation (ISFSI), FSV management made phone calls and visits to nearby businesses and residents, and in 1991, an ISFSI open house was held with nearby residents, the five city councils' members and the Weld County Commissioners were also invited to attend. MAINTENANCE FSV plant management and operations staff routinely monitor plant grounds to eliminate noxious weeds and ensure the grounds are maintained so that soil erosion and dust are minimized. These activities will continue during and after construction activities are complete at both the steam generation and photovoltaic demonstration sites. 19 • • DRAINAGE The construction activities at FSV, including the photovoltaic demonstration project are not expected to change the existing drainage situation at FSV. An extensive drainage management program is in place at the plant to control on-site and off-site drainage. Three copies of Public Service's latest"Stormwater Management Plan"have been provided to Weld County staff as a requirement of this application. LIST OF UTILITY COMPANIES Section III contains a comprehensive list of utility companies located in areas impacted by construction activities discussed in this application. LIST OF ADJACENT PROPERTY AND MINERAL RIGHTS OWNERS The certified lists of surface estate and mineral rights owners is included in the Appendix. 20 411 III. SUMMARY STATEMENT - NATURAL GAS PIPELINE The pipeline portion of this application involves combining three natural gas pipeline projects which are integral parts in Public Service Company's effort to repower the Fort St. Vrain electric generation plant as well as provide for planned reinforcement of natural gas service to communities along the Front Range. While providing natural gas to FSV, the three pipeline sections involved in this application are parts of a program to reinforce natural gas supplies to Front Range communities including Longmont,Boulder,Greeley, Ft. Collins, Loveland and Denver. The scheduling for one of these projects has been advanced two years in order to provide natural gas service to begin the FSV repowering process, slated for January 1, 1996. The Selected Route within this application includes a 20" pipeline beginning at existing gas pipeline sources two miles east of Fort Lupton, extending west 6.5 miles to a valve set known as Tri-Town. This segment of the pipeline is known as CIG/Tri-Town. At Tri-Town a single 24" pipeline turns north 9.5 miles to a second valve set to be located at Weld County Roads 34 and 19 1/2 where the final one mile leg of 12"pipeline extends north and east into the Fort St. Vrain plant. This northern segment from Tri-Town to FSV is known as the Ft. St. Vrain Extension. Again at the Tri-Town, a single 24" pipeline turns south 6 miles to an existing Public Service Company air-blend plant, known as the Yosemite Blend Plant. The Yosemite Blend Plant is located at County Roads 4 and 19. This segment of the Selected Route is known as Yosemite North. See Figure 1 - Vicinity Map or Exhibit 1 for illustrations of the Selected Routes described in this application. The maximum capacity of the 20" CIG/Tri-Town natural gas pipeline is 200 mmcfd (million cubic feet per day). The initial demand at Fort St. Vrain will be 26.36 mmcfd with a projected maximum demand of 56.83 mmcfd by 1999. The remaining capacity will be utilized to deliver natural gas via the Yosemite Blend Plant to an existing valve set at Erie Air Park, to be subsequently delivered to Boulder and Jefferson Counties. A separate special use application, addressing capacity enhancement to the Erie Air Park valve set,will be submitted in late fall of 1994. In total, this application involves 22 miles of pipeline: 6.5 miles of 20" pipeline; 15.5 miles of 24" pipeline; and 1.0 mile of 12" pipeline into Fort St. Vrain electric generation facility. Associated facilities include three above-ground valve sets, requiring sites approximately 100.0 ft. x 100.0 ft. each and one isolation valve set, requiring a site as small as 10.0 feet x 10.0 feet. Future modifications at the Yosemite Blend Plant will be handled by separate application. 21 I IV. DETAILED REPORT - NATURAL GAS PIPELINE ROUTE SELECTION CRITERIA The following are criterion applied to the selection of pipeline routes and to the selection of sites for major and minor natural gas transmission related facilities: Location Consolidate with other existing rights-of-way such as roads, transmission lines, pipelines, etc., depending upon right-of-way width, potential interference and adjacent uses. Follow or utilize property/section lines. Avoid residences and property improvements such as oil and gas wells, ditch headgates. Avoid environmentally sensitive areas; i.e., wetlands. Constructability Accessible, buildable routes. Costs Shortest possible route or strategically placed alignment. Once the needs and benefits are established for the project, the criteria listed above are used as guidelines for a geographic review of the project area. This first site specific review is essentially a "fatal flaw analysis" to identify major geographic or environmental obstacles that would impact construction. When three or four acceptable routes or sites are identified a route inspection and evaluation is done, which is then followed by a review of the respective county assessors maps and records. This compiling of information,which includes parcel identification, and property ownership, is the first step in an analysis of routes for the purpose of minimizing impacts on both private and public lands. As the process continues, existing pipeline-receptive "corridors" are identified. Corridors include existing pipelines, electric lines, roads, ditches, drainage areas, and other natural land features. Once specific routes are determined, they are subjected to environmental considerations, such as wetlands, endangered species, visual impacts, and wildlife habitats. Analysis then considers cultural resources, reclamation, and geologic impacts. When agricultural lands are involved, economic consequences are examined and assessed for proper compensation. A market analysis is requested from a qualified appraiser to establish a base line for right-of-way compensation. Throughout this process, contacts are made and relationships established with local, state, and federal permitting agencies and personnel to inform, and in-turn receive direction, regarding proposed pipeline related facility. The underlying interest in route and site selection is minimum impact at reasonable cost. 22 Alternative Routes Four routes have been considered, for the north/south segments of the pipeline, within a corridor bound by Weld County Roads 19 and 23, 4 and 34. Of the four alternatives considered, two are shown on Exhibit 6 - Alternative Routes Map. Two routes not shown are along WCRs 19 and 21. The route along WCR 19 extend straight north from the PSCo blend plant along the east and west sides of Road 19, to Road 34, where it turns east to Road 19 1/2. The second county road route follows WCR 4 east from the blend plant to WCR 21 where it turns north along Road 21, and Road 21 extended, to WCR 34 at which point it turns west to WCR 19 1/2. A third alternative for the north/south segments, shown as Alternative B on the enclosed map, follows WCR 4 east 1/2 mile, north 1/4 mile, northeasterly 2/3 of a mile to an electric transmission line crossing WCR 21. The route then follows the electric line east an additional 1/2 mile, then north 13 1/2 miles where it begins stair-stepping north and west 1 1/2 miles back to the intersection of WCRs 34 and 19 1/2. The fourth route is discussed later as the Selected Route. For the east/west segment, minor variations of only one alternative were considered. The starting point for the east/west segment is somewhat fixed, in that Public Service Company has an existing tap on the CIG pipeline, immediately south of WCR 16. For that reason, alternate routes for the east/west segment were not considered until the pipeline reached the west side of the South Platte River. Once across the river, a route along WCR 14 1/2 was considered, which is shown on Exhibit 6 - Alternative Routes Map. Other alternatives were minor variations to the Selected Route. The Selected Route and one Alternative Route are also shown on the Alternative Routes Map. Existing Corridors The process of pipeline route selection, in all cases, involves a search for existing utility corridors. Corridors for pipeline purposes include roads, trails, electric transmission and distribution lines, water and sewer lines, and other oil and gas pipelines. In the preliminary review of possible routes for the proposed pipelines, the first two choices were to be adjacent to either Weld County Road 19 or 21 for the north/south leg of this proposal. Both of these routes proved to have excessive conflicts with oil and gas well laterals and gathering lines. In addition, there were numerous conflicts with residential and agricultural improvements which would have caused the pipeline, in many cases, to be routed several hundred feet into the owners property. The third choice was along the half section lines between WCRs 21 and 23, shown as Alternative Route B on the Alternative Routes Map. This choice involved a natural corridor, that being half-section lines, and additionally it intercepted an existing electric transmission line at WCR 16 extended. The third route was subsequently eliminated because of conflicts with ditch headgates,wetlands, and because it added a mile to the pipeline construction and $700,000 in costs. The selected north/south route, utilizes the natural half-section corridor between WCRs 19 and 21, 23 intercepts an existing electric transmission line and has the same relative impact on the areas residents and property as do all other choices. With respect to the east/west segment, the route choice and variations all involved existing corridors. Reasons for Selected Routes Regarding the CIG/Tri-Town or east/west segment, two factors guided the alignment, one an existing pipeline corridor which included a crossing of the South Platte River, and two an acceptable route through or around the City of Ft. Lupton. This segment of pipeline, as shown on the Alternative Routes Map - Exhibit 6, will begin in the vicinity of an existing Colorado Interstate Gas Company pipeline tap approximately 600 feet south of the intersection of Weld County Roads 16 and 33. The Selected Route parallels three existing pipelines west along north edge of Ft. Lupton and across the South Platte River a distance of 5.5 miles to a point 1300 feet west of WCR 23. It then turns south to WCR 14 1/2 which it parallels for 2/3 of a mile to WCR 21. The last 1/2 mile is adjacent to a half section line on WCR 14 1/2 extended. The preferred alternative or Selected Route for the north/south segment is shown on the enclosed Alternative Routes Map along the half section lines between WCRs 19 and 21, from WCR 4 to WCR 34. The route, as proposed, will parallel the south edge of WCR 4 east 1/2 mile from our Yosemite Blend Plant then turns north along the half section lines to the intersection of WCR 34 and WCR 19 1/2. The relative impact on property owners is very similar for all alternatives. The roads (note: for a 24" pipeline, most construction would take place adjacent to the road rather than in the road) offer accessibility, but involve numerous conflicts with property improvements, primarily homes, as well as other pipelines and utilities. Both the Selected Route and Alternative Route B provide greatly improved constructability over the two road locations. Alternative Route B however, adds $700,000 to the cost without an offsetting benefit to property owners. With respect to the north/south segment, considerations included: existing corridors; involvement with residential and agricultural improvements; wetlands; traffic interference; and overall pipeline length. The Selected Route for the north/south segment is the shortest possible route. With few exceptions, the route follows property lines the entire length, and also follows an existing electric transmission line for 4 of the 15 miles. It also has fewer incidents of exposure to wetlands. 24 • • With respect to the east/west segment, the selection process was strongly influenced by the opportunity to follow an existing pipeline corridor for over 5 of the 6.5 miles, most importantly across the South Platte River. The recommended route parallels and is immediately adjacent to existing pipelines of three other companies,and passes through Fort Lupton, which is an area of high natural gas demand for PSCo. In addition, the starting point is in direct alignment with an existing pipeline of PSCo's which is also planned for reinforcement coming from the east through Keenesburg. The following is a length, cost, and size comparison for each north/south alternative. Variations in the east/west segment did not significantly change the length of the pipeline. Alternative Length of 24" Length of 20" WCR 19 15 1/2 miles 7 miles min. $9,300,000 $3,500,000 WCR 21 16 1/2 miles 6 miles $9,900,000 $3,000,000 Selected Route 15 1/2 miles 6 1/2 miles $9,300,000 $3,250,000 Alternative B 17 1/2 miles 5 1/2 miles $10,500,000 $2,750,000 Alternatives B and WCR 21 would add $900,000 and $600,000 respectively to any future projects from northern Weld County. PROJECT DESIGN Detail of Construction From a construction aspect, there are essentially three segments of natural gas pipeline included in this application. A segment from an existing Colorado Interstate Gas Company pipeline, east of Fort Lupton, beginning approximately six hundred feet south of the intersection of WCRs 16 and 33 and ending 6.5 mile west at a valve set located near the center of Section 34, Township 2 North, Range 67 West, also being one half mile west of the intersection of WCRs 14 1/2 and 21. This segment, known as CIG/Tri-Town, is a 20" high pressure steel pipeline designed and tested to operate at 1000psi, with a maximum capacity of 200 million cubic feet (200 mmcf) of natural gas daily. A second segment extends north 9.5 miles from the center of Section 34, T 2 N, R 67 W to a valve set to be located on the north side of WCR 34 and west of WCR 19 1/2 in Section 25 10, T 3 N, R 67 W. From this point it continues north and east for approximately one mile as a service line to Fort St. Vrain Electric Generation Station. This segment is known as the Fort St. Vrain Extension. The pipeline, with the exception of the service line, will be a 24" high pressure steel pipeline, capable of delivering 300mmcf daily at an operating pressure of 1000psi. The third segment extends south 5.5 miles and west 1/2 mile from the center of Section 34, T 2 N, R 67 W to the existing Public Service Company Yosemite Blend Plant. This segment, known as Yosemite North, will initially have a single 24" high pressure steel pipeline delivering up to 300mmcf daily at 1000psi. All piping will be underground with a minimum cover (dirt above the pipe) of four feet, Three above-ground valve sets will be needed, one located south of the intersection of WCRs 16 and 33, one near the center of Section 34, T 2 N, R 67 W, being one half mile west of the intersection WCRs 14 1/2 and 21, and one near the intersection of WCRs 34 and 19 1/2. An in-line, isolation block valve will be needed in the Fort St. Vrain Extension segment to meet DOT code requirements. The location of the block valve is yet to be determined. Subject to availability and contractual agreements, the source and direction of flow of natural gas change frequently. The supply of natural gas for these three segments will initially come from the CIG pipeline area east of Fort Lupton. As other projects come on line and our system develops in this area, this source may be supplemented or possibly eliminated. Plan of Operation Engineering, construction, and operation of the proposed facilities will be performed by or under the supervision of qualified personnel, pursuant to PSCo's company policies, and standards, established by the Department of Transportation as contained in CFR Title 49 Part 192. The requirements of the Occupational Safety and Health Act will be followed in the construction and operation of the subject facilities. PSCo's right-of-way agents or representatives will personally meet with the landowners and/or tenants of the properties to be traversed by the route. During these meetings, landowners' requests for special construction and restoration requirements would be factored into PSCo's overall environmental program. Once the right-of-way acquisition is complete and necessary permits are acquired,a pre-construction survey and staking will take place. This would include staking of the permanent and construction easements at 100-feet intervals. Many of these stakes will remain through cleanup and reclamation. After the rights-of-way have been surveyed and easements secured, portions of the 75 foot wide right-of-way will be cleared of vegetation, rocks, and debris. Topsoil will be removed 26 I and segregated. The right-of-way will then be graded as necessary to provide a relatively level surface for trench excavation equipment and for the safe passage of heavy construction equipment. Debris generated will be removed and properly disposed of at the direction of PSC in conformance with applicable state and county regulations. Care will be taken to maintain irrigation systems and to control erosion. During this initial phase, temporary fences will be established, where necessary, to control livestock and prevent unwanted traffic. The trenching crew will excavate a ditch approximately three feet wide and to a minimum depth of six feet to provide at least 48 inches of cover over the buried 24-inch pipeline. The width at the top of the trench will vary with soil conditions and slope stability. The ditch will be excavated by either a crawler-mounted wheel-type ditch digging machine, a backhoe, or similar trenching equipment. In areas where bedrock is too solid or extensive to trench, pneumatic hammers or blasting will be used to remove the rock. Materials removed during the trenching operation will be temporarily placed on one side of the trench. Where required by the landowner, topsoil will be segregated and conserved for replacement during final cleanup. There are no plans to construct containment structures around the stockpiles due to their temporary nature. Pipe will be shipped in triple random lengths, varying from 50 to 70 feet, and strung along the right-of-way. Pipe joints will be welded together in long sections and placed on temporary supports at the side of the trench. Welds will be visually inspected, X-rayed, and repaired as necessary. The entire pipe will be coated and electronically inspected to locate any faults or voids in the coating. The pipe will then be lowered onto the trench. The trench will then be backfilled with previously excavated materials and the right-of-way graded to pre-construction contours, except for a slight crown of soil to compensate for the natural subsidence of the backfill. In rock areas, the pipeline is protected with appropriate padding material. After backfilling, a cleanup crew will remove all materials and debris from the site. Excess trench materials will be spread uniformly over the construction zone or removed to a suitable location. The final process will be to place the stored topsoil over the trench. Slopes will be stabilized by seeding in rangeland areas. Treatments to cultivated areas will be as requested by the landowner. Fences will be restored to their pre- construction condition or better. Work Force The anticipated size of the work force will peak at approximately 100 people. The entire work force will be temporary for the 150 day duration of the project. Ongoing operations and maintenance will be accomplished with existing employees. 27 • i Construction Equipment Listed below are the types of equipment to be utilized in the construction of this project: Type Number sae Backhoes 5 Cat 235 Lowboys 4 Bulldozers 3 Cat D7 Side Boom Crawlers 8-12 Cat D7 Trenchers 1 Cleated Track Compactors 2 Flatbeds 2 2 Ton Welder Units 10-15 Pickups 15-20 Hydrostatic Testing The pipeline will be hydrostatically tested in accordance with requirements of 49 CFR Part 192. The hydrostatic testing procedure will be conducted by a contractor. The testing will occur in segments between valve sets. One segment will extend from the CIG natural gas line tie in to the Tri—Town valve set, a distance of 6.5 miles. A second segment will extend from the Tri—Town valve set to the Yosemite Blend Plant, a distance of 5.5 miles. The third test segment will extend from the Tri—Town valve set to Fort St. Vrain Electric Generation Plant, a distance of 9.5 miles. An in—line, isolation block valve will be needed in this segment to meet Department of Transportation code requirements. The location of this valve is yet to be determined. Hydrostatic testing will occur in the first segment completed. The water will then be left in the completed pipeline segment for subsequent testing of the remaining segments. As a result, the amount of water required for testing will be considerably reduced. Furthermore, the water used for testing will only need to be discharged once. The testing will involve the use of up to approximately 5,265 gallons of water. Water will be purchased from water owners or proper water authorities. The discharge of hydrostatic test water will be done under a National Pollutant Discharge Elimination System (NPDES) permit from the Water Quality Control Division of the Colorado Department of Health, Environmental Quality. Since the water will not be toxic, it is anticipated that the water will be discharged into sewers or irrigation ditches. 28 • • PROJECT COSTS The project costs for the Selected Routes are $15,430,000. These costs include right-of-way acquisition, surveying, construction, and reclamation. The cost range for the alternative routes is $16,500,000 to $22,000,000. These estimates include additional right-of-way costs, additional pipe, and increased cost due to difficulty of construction. PROJECT SCHEDULE The three pipeline segments are scheduled to start construction in mid-July, 1995. Subject to minimum stream flows, the crossing of the South Platte River could be done independently of other construction, as early as October of 1994. The actual start date may vary, subject to availability of construction contractors. The completion date is fixed at December 31, 1995. Construction period is expected to be 150 days from first disturbance through reclamation. LAND USES Description of Lands With the exception of roads and limited wetlands, the entire project of three pipeline segments involves lands dedicated to agricultural purposes. Approximately 40%is irrigated, 20% are livestock uses, 30% pasture or dry land, and 10% fallow. Easements Approximately 52 separate easements will have to be secured for the project. Easement widths will vary from 50.0 feet permanent with 25.0 feet temporary construction easement, to 75.0 feet permanent without any additional construction easement needed at this time. There may be some variation in these requirements to accommodate boring pits and to deal with impacts of terrain. Compensation will be subject to the value of the property with additional compensation for damages and reclamation, when applicable. Access Easements will be accessed by way of existing roads. During construction, contractors and employees will be required to limit and control access and vehicular traffic in a manner that will protect the public and livestock from hazards associated with construction. 29 • • Road Crossings There are 21 road crossings involved with the project, two of which are Colorado State Highways 52 and 85, one for the City of Ft. Lupton, and the remaining are Weld County roads. To avoid unnecessary disturbance, all roads possible will be open cut. Acreage Approximately 200 acres of land will be impacted by the proposed pipeline construction. Eminent Domain Public Service Company of Colorado, by state statute, is granted the right of eminent domain. There is a likelihood, with a project of this size, that the right of eminent domain will have to be exercised and condemnation proceedings initiated with one or more parties. In any event, every option and alternative will be reviewed, and negotiated if possible,prior to entering into the condemnation process. It should be noted that this is the least desirable action that will be taken in any easement acquisition. PROJECT IMPACTS & MITIGATION This section of the "DETAILED REPORT' describes project impacts and proposed mitigation measures to address those impacts. Agricultural Lands Included in the impacts on agriculture, are loss of crops in the construction areas, reduced yield with the next crop, interference with irrigation, and general interference with operations during construction. Occasionally there can be a loss of livestock from gates left open and fences down as well as loss of poultry livestock from the construction activity itself. Mitigation - To mitigate crop loss and damage, property owners or lessees will be compensated by the acre and relative crop at the rate of 200% if construction occurs during a growing season, and 100% if construction takes place before crops are planted or after being harvested. Losses are calculated according to acreage effected, historic prices and yields for the current crop (source of data, Colorado Agricultural Statistics handbook) and then discussed and confirmed with the property owner or lessee. In addition, contractors are required to segregate topsoil in a manner that will insure that the topsoil is returned to the top of the trench. 30 IP I Care will be taken to maintain the integrity of all irrigation systems. It is anticipated that operators will have to be consulted, and compensated accordingly, to insure continued operation of irrigation systems during and following construction. Mitigation of impacts on grazing and livestock will require considerable input from growers to determine fair compensation and control of loss. With respect to revegetation of grazing and non-specific use areas, Public Service prefers to use specialized reclamation contractors which can be easily recalled if initial reclamation attempts are unsuccessful. Soils The proposed pipeline crosses soils which have been grouped into the following four soil associations (Crabb, 1980): Midway—Shingle: Shallow, moderately sloping to strongly sloping,well drained clays and loams formed in residuum from calcareous shale; Ulm—Nunn: Deep, level to gently sloping, well drained clay loans and loans formed in alluvial and eolian deposits; Wiley—Colby—Weld: Deep, nearly level to moderately sloping, well drained silt loans and loams formed in calcareous eolian deposits; and Nunn—Haverson: Deep, level and nearly level, well drained loans and clay loans formed in alluvium. Along the Yosemite North segment, soils with a moderate or high erosion hazard will occur in T1N R67 W Sections 3, 10, 15, and 27. The final area of soils with moderate or high erosion potential will occur along the CIG/Tri—Town segment in Sections 35 and 36, T2N, R67W, and in Section 31, T2N, R66W. All other soils crossed by the pipeline have a low hazard for water or wind erosion. Mitigation - In areas with a moderate or high potential for water or wind erosion, PSC will pro-actively use best management practices to minimize erosion at the site and promote soil stabilization following installation of the pipeline. Construction activities will not take place in these areas when soils are saturated. 31 • Vegetation Four major vegetation types occur within the right-of-way. These vegetation types are pastureland, agricultural fields, home sites, and wetlands. Of these, agricultural fields are by far the most predominant. All areas have been disturbed to some extent by human activities. No critical or unique habitats, such as native shortgrass prairie, were observed during the site reconnaissance. The agricultural fields consisted of winter wheat, other grain crops, and alfalfa. These areas are typically a monoculture of one agricultural species and do not support any vegetative diversity. Any impacts to vegetation from the pipeline in these areas will be insignificant. The pastureland vegetation type was the second most common vegetation type within the right—of—way. Grazing on these areas varied from heavy to light. Plant species associated with these areas included, crested wheatgrass (Agropyron cristatum), western wheatgrass (Agropyron smithii), yucca (Yucca spp.), cheatgrass (Bromus tectontm), sunflowers (Hellianthus annuus), and buffalograss (Buchloe dactyloides). In general, these areas do not support many native shortgrass prairie species. Also, these areas are highly disturbed from grazing. Impacts from the pipeline construction are not expected to be significant due to the lack of significant habitat types within these areas, i.e., shortgrass prairie. Additionally, large amounts of this habitat type surround the right—of—way. The disturbed habitat type typically occurs in roadside ditches and near buildings. Plant species associated with these areas are typically either weedy or planted exotics. Species such as bindweed (Convolvulus arvensis), sunflowers, clovers (Melilotus spp.), and bluegrass (Poa spp.) are typical in these areas. Impacts from the pipeline are expected to be minimal within this vegetation type due to the highly disturbed nature in which they exist. Wetland plant species observed in the right—of—way include curly dock (Rumex crispus), reed canarygrass (Phalaroides arundinacea), cattail (Typha spp.), milkweed (Asclepias spp.), sedges (Cara spp.), rushes (Juncus spp.), and foxtail barley (Hordeum jubatum). Specific wetlands locations are addressed in the next section. A small riparian corridor, which cannot be avoided at the proposed crossing, also exists along the South Platte River crossing. Plant species associated with this area include cottonwood (Populus spp.), willows (Salix spp.), curly dock, hemlock (Cicuta spp.), sedges, and rushes. The riparian corridor is restricted to a narrow band along the river. Impacts from construction are not expected to occur if proper wetland construction practices are utilized. 32 • Air Resources The climate of Weld County is generally characterized by low precipitation, low average relative humidity, and large annual and diurnal temperature ranges. The climatological record from Greeley, Colorado (NOAA, 1992) shows average monthly maximum temperatures ranging from 89°F in July to 39°F in January. Average minimum monthly temperature range from 58°F in July to 12°F in January. Average annual precipitation for the area is 13.97 inches. Approximately 60 percent of this precipitation occurs from May to September. From late fall to mid spring, the area receives about 35 inches of snow. Measurable amounts of precipitation(rain or snow) can be expected about 85 days per year. National Ambient Air Quality Standards (NAAQS) have been established by the U.S. Environmental Protection Agency and the Colorado Department of Health for six air pollutants, known as "criteria pollutants". The purpose of the NAAQS is to protect the public health, since pollutant concentrations greater than the standards are considered potentially harmful. For this proposed project, pollutants of interest are carbon monoxide emitted from construction vehicles and particulate matter associated with construction activities and wind blown erosion from devegetated land along the pipeline right—of—way. Since 1987, the particulate matter standard is PM10, defined as suspended particles with an aerodynamic diameter of ten microns or less. The State of Colorado has adopted the same standards as the NAAQS. The National and State of Colorado standards for PMIo and carbon monoxide are as follows: NATIONAL AMBIENT AIR DUALITY STANDARDS POLLUTANT AVERAGING TIME CONCENTRATION Carbon Monoxide 1 hours 35 ppm (40 mg/m3) 8 hour* 9 ppm (10 mg/m3) PMIo Annual 50 ug/m3 arithmetic mean 24 hour* 150 ug/m3 * Concentration not to be exceeded more than one time per year in averaging time period. ppm - Parts of pollutant per million parts of air mg/m3 - Milligrams pollutant per cubic meter of air at standard atmospheric conditions (pressure 29.92 inches Hg, temperature 25°) ug/m3 - Micrograms pollutant per cubic meter of air at standard conditions 33 S Greeley, in Weld County to the north of the project area, has an attainment status for PM10 and a non-attainment status for carbon monoxide. In other words, PM10 levels are below the NAAQS. Greeley has a non—attainment status for carbon monoxide based on levels slightly above the NAAQS in the past few years. However, carbon monoxide levels have been below the NAAQS since 1992, and the non—attainment status for carbon monoxide will probably change to attainment within the next five years (Silverstein, 1994). Gaseous emissions from construction vehicles and equipment will be short term and minor for the expected 120—day duration of the pipeline construction. Furthermore, these emissions will be minuscule when compared to vehicle emissions along the two major transportation corridors, Interstate 25 and U.S. Highway 85, both within six miles of the project area. For these two reasons, the project will not have a significant impact on the carbon monoxide levels in the region. PM10 emissions, as fugitive dust, will result from soil disturbance during the 120—day pipeline construction period. Dust generated after several days without precipitation will be controlled by watering of the right—of—way. After construction is complete, portions of the right—of—way within the 95 percent of farm lands will remain bare until crops are planted. PSC will submit a Fugitive Particulate Emissions Control Plan to the Colorado Department of Health, Air Pollution Control Division, for their approval. The plan will outline the frequency which the bare ground along the right—of—way will be watered. As a result, the fugitive dust impacts will be minimal until revegetation and planting is completed within one year. Water Resources The major water bodies in the project area are the South Platte River and a perennial tributary, the Big Dry Creek. Numerous other small intermittent streams and irrigation ditches cross the region. Wheeler Lake in T3N R67W, along the border of Sections 27 and 34, is the only lake near the pipeline route. Specific locations of these minor streams and ditches are listed below in the Wetlands section of this report. The Tri—Town/CIG segment of the proposed pipeline will cross the South Platte River and its floodplain in the N 1/2 of Section 31 T2N R66W. The floodplain is about 0.8 miles wide at this point. The average discharge for the South Platte about 12 miles upstream of this point was 553 cfs (cubic feet per second) for the period 1976-1993 (Ugland et al., 1994). The maximum daily discharge for the 67 year period of record was 13,200 cfs on May 7, 1973, an amount 24—fold over the average. Turbidity at this station has averaged 14.4 NTUs (nephelometric turbidity units) for the period 1989-93. Turbidity has ranged from 1.1 to 100 NTUs during this period. It is generally highest during peak flow periods. 34 The Yosemite North segment will cross Big Dry Creek in T1N R67 Section 22. At its confluence with the South Platte River, about 5 miles downstream of the crossing, Big Dry Creek has had an average discharge of 36.7 cfs (cubic feet per second) from 1991 to 1993 (Ugland et al., 1994). The creek is subject to considerable flood surges as evidenced by a maximum daily discharge (August 15, 1992) of 338 cfs during the same period. Construction across the South Platte and its floodplain will take place during late fall, 1994, or early fall, 1995. In either case, the crossing will occur during low water flow periods. The river crossing will be accomplished in one to three days. Trenching will take place by use of trackhoes. Excavated materials will be placed downstream of the trench in piles, allowing normal stream flows to continue relatively unabated. Following placement of the pipeline, the trench will be backfilled with trackhoes to bring the stream bed to original grade. Maintenance and refueling of equipment will take place at least 150 feet away from the streambank. Equipment not required in—stream for the crossing will cross the river using existing bridges. A slight increase in turbidity and sedimentation will occur downstream for less than a week as a result of the in—river construction. Because the minor impacts will be directly related to flow, construction late in the fall will have the least impacts. Construction in the Big Dry Creek floodplain will take place in early fall, 1995. PSC will attempt to minimize placement of construction equipment in the streambed or areas of the floodplain where soils are saturated. Construction equipment and personnel will make use of the present road and bridge to the extent possible. Pipeline trenching may encounter shallow groundwater in the following areas(Crabb, 1980): CIG/Tri—Town segment T2N R67W Sections 35 and 36 T2N R66W Sections 31, 32, and 33 Fort St. Vrain Extension segment T2N R67W Sections 3 & 27 T3N R67W Section 34 In addition, the pipeline corridor will be located close to several domestic wells. PSC will use appropriate mitigation measures in these areas. No hazardous materials, chemicals, fuels, or lubricating oils will be stored or used within 150 feet of wells or any groundwater exposed by trenching. Furthermore, no vehicle or equipment maintenance or refueling will be conducted within 150 feet of these wells or any exposed groundwater. 35 Wetlands Jurisdictional wetlands along the proposed route were identified using the National Wetlands Inventory maps for the following USGS 7.5 minute quadrangle maps: Erie, Frederick, Fort Lupton, Gowanda, and Platteville. These areas were verified during a site reconnaissance on June 23, 1994. The only wetlands of significant size are associated with the South Platte River near Fort Lupton and Wheeler Lake. The proposed route will cross the South Platte, but will deviate around the Lake Wheeler wetlands. Other wetlands are in narrow bands associated with small streams and irrigation ditches. These wetlands are typically 10 to 20 feet wide. The wetlands identified along the selected pipeline routes are as follows: Wetland Type* Water Body Location R4SBKC Branther Ditch T1N R67W S1/8 Sec 22 PEMY Big Dry Creek1'2 T1N R67W S1/4 Sec 22 R4SBKC Branther Ditch T1N R67W N1/8 Sec 22 R4SBKC Bull Ditch T1N R67W N1/2 Sec 15 R4SBKC Branther Ditch T1N R67W midpoint Sec 3 PEMY Little Dry Creek2 T1N R67W N1/4 Sec 3 R4SBKC Branther Ditch TUN R67W S1/4 Sec 34 PEMY Unnamed Drainage T2N R67W N1/8 Sec 27 R4SBKC Coalridge Ditch T2N R67W S1/4 Sec 10 R4SBKC Lupton Bottom Ditch T3N R67W S1/2 Sec 34 PFLY Wheeler Lake2 T3N R67W border of Sec 34,35 PFLY Unnamed Overflow Catchment T2N R67W midsection 34 POWKF Brantner Ditch T2N R67W W1/4 Sec 35 R4SBKC Lupton Bottom Ditch T2N R67W W1/4 Sec 35 PFOW, RSBBW South Platte Riverl,2 T2N R66W N1/4 Sec 31 PEMW Platteville Ditch T2N R66W NE1/4 Sec 31 R4SBKC Fulton Ditch T2N R66W N1/8 Sec 33 1Potential habitat for Ute—ladies' tresses (Spiranthes diluvialis) 2Jurisdiction Wetlands *Wetlands Type (U.S. Department of Interior, Fish and Wildlife Service, National Wetlands Inventory) R4SBKC — Riverine in intermittent streambeds, artificially and seasonally flooded PEMY — Palustrine, emergent, saturated, semipermanent, seasonal PFLY — Palustrine, flat land, saturated, semipermanent, seasonal POWKF — Palustrine, open water, artificially flooded, semipermanently flooded PFOW — Palustrine, forested, intermittently flooded, temporary RSBBW — Riverine, streambed, saturated, intermittently flooded, temporary 36 Construction of the pipeline through these wetland areas will be covered under a Nationwide Permit from the U.S. Army Corps of Engineers. Impacts to wetlands will be minimized by PSC's following of the Best Management Procedures for wetland construction. Wildlife Habitats The general wildlife resource along the pipeline routes is upland in nature. However, semi—aquatic species may occur in areas of suitable habitat. Several habitat types occur within the right—of—way. These areas range from grazed pastureland and agricultural fields to wetlands. However, the majority of the area is pasture and agricultural land. Wildlife associated with the pastureland habitat include coyotes (Canis latrans), badgers (Taridea taxes), and red foxes (Vulpes fulva). In addition, many species of birds utilize these areas for both nesting and foraging. These species include western meadowlarks (Sturnella neglecta), horned larks (Eremphila alpestris), black—billed magpies (Pica pica), red—tailed hawks (Buteo jamicensis), and American kestrels (Falco sparverius). Pronghorn antelope (Antilocapra americana) may utilize these areas. However, the amount of human disturbance and grazing pressure within these areas will limit the attractiveness of these areas for antelope. Wildlife habitat within the agricultural habitat areas is very limited. This is due to the tendency of these areas to support only one plant species. Some species such as house sparrows (Passer domesticus), mule deer (Odocoileus hemionus), ring—necked pheasants (Phasianus colhicus), and horned larks may use the area. Generally, these areas are lacking significant wildlife habitat. Wetland areas along the pipeline route are typically small and linear in nature. Although these areas are small, they are important for wildlife. Wildlife associated with these areas include red—winged blackbirds (Agelaius phoeniceus), raccoons (Procyon lotor), muskrats (Oniulatra zibethica), skunks (Mephitis mephitis), and various amphibians. In conjunction with the wetlands, the riparian habitat type within the South Platte River corridor also supports a wide variety of wildlife species. Species include various hawks, owls, muskrats, and raccoons. The disturbance areas and home sites provide marginal habitat for wildlife because of the amount of vegetation previously removed during construction. One species typically associated with these areas is deer mice (Peromyscus maniculatus). Mitigation -Where wildlife habitats are natural areas, PSC will limit activity as much as possible (i.e. - remove equipment and construction debris as soon a construction is complete) and limit access for other construction. Employees will be asked to minimize the disturbance of any wildlife encountered. The same attitude and approach will be observed during reclamation. 37 • Threatened and Endangered Species Several threatened and endangered wildlife species potentially occur within the pipeline route. These species include bald eagles (Haliaceetus leucocephalus), black—footed ferrets (Mustela nigripes),and whooping cranes(Grits americana)(Carlson 1994,pending).Although these species may occur in the area, none were observed during the site reconnaissance. However, potential habitats were observed. Bald eagle habitat consists of both nesting habitat and roosting habitat. The nesting habitat is typically occupied from November 15 through July 30. Within the Selected Route right—of—way, no nesting sites are known to occur (Carlson 1994 pending). Roosting habitat is typically occupied during the winter from November 15 through April 1 (CDOW 1991). However, the most critical period is from November 15 through March 15 (CDOW 1991). Roosting habitat is primarily located in riparian areas. Canopies may be either open or closed depending on weather conditions. Some roosting habitat may occur within the South Platte River corridor. Therefore, construction of the pipeline will not occur from November 15 through March 15 if roosting eagles are observed within a 1/4 mile radius of a proposed crossing (CDOW 1991). Whooping cranes may also potentially occur within the Platte River corridor. Typically, usage of this area will be as a migrational stopover area. The cranes may utilize the area on both their fall and spring migration. However, sightings of whooping cranes are limited on the front range. Sites typically used by the cranes are grain fields with large amounts of horizontal visibility, wetlands with low vegetation for loafing. In addition, roosting habitat with low vegetation to provide good visibility and occurring well away from human disturbances are utilized. All the areas used by the crane occur within three miles of large expanses of water or rivers. Impacts to the crane are be expected to be minimal for several reasons. First, no cranes have been documented to occur in the general area. Second, the South Platte River crossing provides the only suitable roosting habitat within the right—of—way. However, this area is in close proximity to the City of Fort Lupton and therefore may not be attractive for the cranes. Although grain fields are crossed throughout the right—of—way, the minor amount of disturbance related to the project will not influence any cranes which may occur in the area. Potential habitat for the black—footed ferret was observed within the right—of—way. This potential habitat consists of black—tailed prairie dog (Cynomys ludovicianus) colonies. The prairie dog provides nearly all the habitat requirements for the black—footed ferret. The U.S. Fish and Wildlife Service has determined that a minimum of 80 acres of active prairie dogs is sufficient to support ferrets (FWS 1989). No prairie dog colonies meeting these requirements were observed during the site reconnaissance. Therefore, no impacts to black—footed ferrets are anticipated. 38 Within the right—of—way, three wetland areas occur with the potential for Ute—ladies' tresses orchid (Spiranthes diluvialis), a federally listed threatened plant species. The U.S. Fish and Wildlife Service has established guidelines for surveys to determine the absence or presence of this plant. The PSC Pipeline project will meet the specified criteria since it will cross wetland areas which are below 6,500 feet elevation and are within the 100—year floodplain of the South Platte River and its perennial tributaries, in this case the Big Dry Creek. A survey of the potential areas was conducted on August 2, 1994 by a consultant plant ecologist. No individuals or populations of Spiranthes diluvialis were found within the wetland areas identified for this project. A copy of "Plant Survey for Spiranthes diluvialis" has been provided to Weld County planning staff. This report contains the methodology and results of the survey. Visual Impacts The project area can be characterized as gently rolling agricultural land with wide expansive vistas. US Highway 85 is a north—south route through the eastern portion of the CIG/Tri- Town segment. This is the locations where most people will view the project area. Short term visual impacts will occur during the 150—day construction period. The presence of construction equipment will be noticeable to travelers along US 85. This impact will not only be very short term, but the impact should also be minor because of the following reason. In the area of US 85, the pipeline is crossing at substantially right angles and will be observed only during approach, crossing and departure. In most other cases, the pipeline route is aligned parallel and adjacent to, or within 1/2 mile of, an existing paved or improved road. Viewed from a distance, the pipeline construction may be perceived as a normal expansion or widening of the road system in the area. After construction is complete, the pipeline construction right—of—way will have a minor but short term visual impact for two reasons. Because 95 percent of the route is agricultural land, crops will probably be planted within a year, and thus the right—of—way will be revegetated quickly. Similar to construction activities,the right—of—way will be parallel and adjacent to or be located within 1/2 mile of the existing road system. Accordingly, the non—revegetated portions will tend to blend in with the existing road system until revegetation is complete. The only permanent above ground facilities will be valve sets. These valve sets will be limited to sites 100 feet by 100 feet and will be less than six feet high. These valve sets will hardly be noticeable at distances beyond a half mile. 39 Mitigation - Once construction is complete, agricultural land will be returned to post- harvest conditions. Evidence of construction will then be eliminated with the planting of the next crop. With respect to pasture lands and natural areas,revegetation will take place immediately following construction and then monitored each growing season until reclamation is successful. Above-ground facilities are painted environmentally compatible colors and maintained in an aesthetically pleasing manner, consistent with good safety practices and standards. Mineral Resources The proposed pipelines will have no relative impact on mineral resources. Gravel or coal extraction will require coordination between the operator and Public Service Company. Mitigation - No mitigation measures are proposed. Dust & Erosion Fugitive dust and minor erosion are anticipated during construction. See "Air Resources" discussion in this section. Mitigation - During construction fugitive dust will be controlled with water. Following construction, PSCo will work closely with landowners to see that the land is returned as quickly as possible to a typical post-harvest conditions. Other lands will be reseeded and mulched, with a tackifier, if necessary, to prevent further soil damage. All pasture and natural lands will be monitored regularly for noxious weeds which will be controlled by a licensed contractor or the landowner or lessee, if appropriate. See "Air Resources" discussion in this section. Drainage No changes in historical runoffs or runoff routes will be required as a result of this project. Application for a Colorado Stormwater Discharge Permit will be made at the appropriate time and made available to Weld County upon request. Historical & Archeological Resources During July, 1994, a Class I cultural resources records search of the project area was conducted through the Colorado State Historic Preservation Office. The records search documented all previously recorded sites of prehistoric or historic cultural resources that might be affected by the PSC Pipeline project. As part of the search, the eligibility of 40 S known sites crossed by or located near the proposed pipeline route was reviewed for nomination to the National Register of Historic Places. The records search indicated three Class III and one Class II surveys have been completed in the general area. These surveys included a highway corridor, a utility line corridor, a pipeline compressor station, and a Weld county—wide farm and ranch inventory. Various artifacts located have been bone debris, charcoal ash, a railroad siding, a farm complex, and a variety of miscellaneous tools, dishes, and household fragments. None of these findings have been determined for listing on the National register of Historic Places. The PSC Pipeline project will not impact cultural resources for three reasons. First, nothing of historical significance has been discovered in the area. Next, the pipeline will parallel existing pipelines. No cultural findings were discovered during the construction of these pipelines. And finally, the construction crews will be instructed to immediately stop work if anything is found which may be of historic significance. At that point, the construction foreman will immediately notify PSC who will in turn notify the Colorado State Historic Preservation Officer. Local Governments and Special Districts Likely impacts on local agencies and special districts will be with county road maintenance, ditches, and traffic during construction. Post-construction impacts will be essentially limited to fire protection districts for emergency purposes. There are no other utilities or services required as a result of this proposed project. The impacts to roads and ditches will be addressed through their respective permitting processes. HAZARDS & MITIGATION In addition to the hazards associated with the actual construction there are marginal hazards from fire and explosion associated with the operations of the pipeline. Mitigation -Nationwide, experience has shown the primary cause of natural gas pipeline accidents, resulting in fire and/or explosion, is third party damage, i. e. outside force, such as construction or excavation equipment. To minimize the associated hazards, Public Service Company has an ongoing pipeline marker program as well as a continued commitment to the "One Call" program. The Company also engages in frequent safety awareness programs, using various media sources and its own billing functions as a means present the information. With this said, it should be noted that pipelines have the best safety record among all major U. S. transportation systems. 41 EMERGENCY PROCEDURES Three copies of the Gas Emergency Plan have been provided to Weld County staff with this application. WATER REQUIREMENTS Only two water uses are involved with construction and no water is needed for operations. The construction needs are for dust control and injection into the finished pipeline for testing purposes. In both cases,water will be purchased from water owners or proper water authorities. Water used for testing, which is non-toxic, can be disposed of through ditches, sewers, or irrigation. See "Hydrostatic Testing" information previously discussed for additional information. GEOLOGICAL HAZARDS The proposed pipeline will cross unconsolidated eolian deposits in upland areas and unconsolidated alluvium in river and stream valleys as well as other low—lying areas (Stoister, 1965). These materials have been deposited during and following the Pleistocene epoch ("Ice Age") of the past 2 million years. The alluvial deposits are a source of sand and gravel. There are quarries in the area, but the proposed pipeline will not cross or interfere with any current operations. These unconsolidated materials overlie shale of the Dawson Formation which was deposited during the upper Cretaceous Period approximately 70 million years ago (Stoister, 1965). These strata and those below them have been slightly downwarped into the Denver Basin, a structural feature in which commercial quantities of oil and gas have collected. Several oil and gas wells are located close to the proposed pipeline route. The pipeline will maintain sufficient distance to avoid interfering with their operations or preclude the development of additional wells. Trenching for the pipeline may encounter bedrock in areas of shallow soils along a 0.1 mile segment through a shallow bedrock area just south of Little Dry Creek in Section 3, T1N, R67W, along the Yosemite North segment (Crabb, 1980). Trenching in the remainder of the corridor will be through unconsolidated materials. This area of Colorado lies within seismic risk zone 1, a relatively stable area with regard to earthquake activity (Algermissen, 1969). Minor damage could be expected from distant earthquakes. Significant slope failure will not be expected along the proposed corridor because most of the terrain is nearly level to slight sloping (0 to 9 percent). 42 PUBLIC MEETINGS Pipeline construction does not generally create the same level of public interest as that of more visible improvements. Public meetings are therefore limited to the hearing(s) that occurs during the permitting process. Experience will indicate that the main interest in the pipeline will be generated from those people most directly affected by construction. All individuals directly affected by construction or operations, will be contacted prior to construction. CONFORMANCE WITH COMPREHENSIVE PLAN There appear to be no conflicts with goals of the Weld County Comprehensive Plan. The proposed pipeline is essentially a traveler through the county, having only a marginal effect on the County's land, water, transportation,wildlife habitats, and population. These effects are largely generated during the construction phase and are limited to a 150 day duration. The facility itself neither promotes nor inhibits urban growth. Its most significant effect, with these projects, is on agriculture and again is limited to the construction period. Pipelines can and have in fact shown to be an asset to a community by providing buffering within residential developments as well as providing a corridor for other utilities and recreational uses. 43 LIST OF LOCAL GOVERNMENTS & SPECIAL DISTRICTS A list of local governments and special districts associated with the projects discussed in this application are shown below.

Saint Vrain Gas Pipeline Dear Sir; In response to the above noted case, the following comments are offered with responses requested. 1. The drawings and specifications do not indicate the number of in-line valves to be installed. The only valves noted are at the Yosemite plant and at the Tri-Town junction point. Should these be the only valve locations, nearly 100,000 cu. ft. of gas under pressure could escape after valve shut-down in an emergency situation. Keep in mind that down would only occur after arrival of authorized personnel . 2. The pressure of the gas within the pipeline was not determined from the specification documents. Please provide. 3. The manner in which the pipeline is to be marked was not specified in the specifications. Please provide information as to the manner of marking and the locations of markers. 4. The pipe material specifications, including working pressures, burst pressures and wall thickness were not specified in the specification documents. Test pressures were also not related to the manufacturers recommendations. Please provide complete specification information, manufacturer's installation and testing procedure recommendations. Should there be any questions concerning these comments, please do not hesitate to contact this office. Thank You.

The information was reviewed by Courtney Crawford and Danielle Hosier, the Division's officers in South Weld, and myself. In this letter you will find the Division comments on the proposal. It should be pointed out that the Fort St. Vrain facility is located in the valley created by the confluence of the South Platte and St. Vrain Rivers. The proposed pipeline route parallels the South Platte between one half and three miles west of the river channel . Areas along river floodplains in Weld County can be described as low elevation, cottonwood-willow, riparian habitat. From a wildlife standpoint this habitat type is the most productive and highly diversified ecosystem in the West. For example, of the 438 bird species found in our State over half are part-time or permanent residents of lowland cottonwood forests. An analysis of this system done in northeast Colorado showed that vertebrates dependent on low elevation riparian habitat include: 5 amphibian, 10 reptile, and 43 mammalian species, roughly 1/3 of Colorado's terrestrial fauna. This is remarkable in light of the fact that the low elevation, cottonwood-willow ecosystem occurs on only 3% of the land in Colorado. Therefore, the wildlife species list included in the Public Service Co. proposal should be viewed as a partial list that merely scratches the surface of this rich biological system. Many species including white-tail deer, mule deer, beaver, wild turkey, wading birds, shore birds, miscellaneous waterfowl , miscellaneous fishes (both game fish and small fish) , predators, scavengers and herptiles are directly dependent on the riverbottom. Any change in this system may adversely impact one or more wildlife species. The aesthetic quality of the valley, the history of the area, and the diverse flora and fauna found in the riparian corridor combine DEPARTMENT OF NATURAL RESOURCES,lames S. Lochhead, Executive Director X WILDLIFE COMMISSION,Thomas M. Eve-Chairman, Louis F. Swift-Vice Chairman, Arnold Salazar-Secretary, Jesse Boyd-Member, Eldon W. Cooper-Member, Rebecca Frank-Member, William R. Hegberg-Member, Mark LeValley-Member aw ra a • . 2 to make the South Platte system a valuable recreational asset for Weld County. The river bottoms are dotted with hunting clubs and leases. People canoe the rivers, pursue watchable wildlife opportunities, photograph vistas and wildlife, and seek the many historical sites along the South Platte Trail . Development in and near riverbottoms should protect the aesthetic quality and recreational value found in these areas. With regard to the Public Service Company Proposal the Division would recommend the following: 1. A nest site for the American Bald Eagle, listed on both State and Federal Threatened-Endangered Species lists, is located within 1/2 mile to the northwest of the existing FSV facility. This site has been active in recent years. Bald Eagles are extremely sensitive to human disturbance during the nesting season. Construction and development within 1/4 mile radius of the nest site should be avoided. Construction and other activities involving large numbers of people and vehicles should be curtailed if eagles are seen in the area during the critical nesting period between February and July. Courtney Crawford, phone 339-5208, will be available to identify the nest site if necessary. 2. The Division prefers the selected pipeline route designated on the map over the alternate route. 3. Revegetation efforts along the pipeline route and other construction areas should use seed types and plant materials selected specifically for the habitat type being impacted. The pipeline will cross riparian bottoms, farm ground and upland pasture land among other habitat types. It makes little sense to use a bottom land seed mixture in an attempt to revegetate a disturbed upland prairie site and vice versa. 4 . Construction activity will require the removal of trees and woody vegetation along the pipeline route and at the plant site. Trees and woody plants removed should be replaced on a minimum one to one basis as part of the revegetation effort. Plantings should use plant species native to the habitat type being repaired. Installation of plantings should use mulch with weed barrier to increase survival and reduce maintenance of the plantings. Shrub thicket plantings should be used to increase shelter for ground dwelling species. Use of elms and russian olive trees should be avoided on riparian sites. 5. The pipeline corridor crosses several Black-tailed Prairie Dog colonies. Prairie dog towns are used as nest sites by Burrowing Owls. Prairie dog colonies that will be disturbed during Burrowing Owl nesting season, May through September, should be surveyed for owls prior to onset of construction. Ideally, pipeline construction should occur during the months Burrowing Owls are not actively nesting. If owls are found using burrows in areas to be developed construction should be delayed until the young are • • 3 fledged. Alternatively, construction activities could be shifted to create a 500 foot buffer around active Burrowing Owl nest sites. Danielle Hosler, phone 833-3647, is available to help identify the location of prairie dog colonies along the pipeline route. The Division of Wildlife has appreciated the opportunity to review and comment on this proposal. With all interested parties working together the South Platte River valley will continue to be an invaluable recreational and natural resource amenity into the 21st century. Please feel free to contact me at 352-2143 if we can be of further service to you or the Public Service Company.

The Service finds the report acceptable and agrees that the threatened species Spirwuhes diluvialis (Ute ladies'-tresses orchid) is not present within the subject areas where the survey was performed. Thus, the Service concurs with your determination that the proposed project should not adversely affect the continued existence of this orchid. We appreciate your interest in conserving rare species.

As to in-line valves, Department of Transportation (DOT) requires valves no more than eight miles apart. Therefore, as you mentioned there will be valves at the Yosemite Plant and Tri-Town junction. There will also be a valve at the intersection of Weld County Road 19 1/2 and WCR 34, south of Fort St. Vrain Generation Facility, and also an in-line valve approximately four miles south of the Fort St. Vrain valve set. Regarding the pipeline pressure, the pipeline will be tested to 1,800psi for a MAOP (Maximum Allowable Operating Pressure) of 1,200psi. The actual day-to- day operating pressure is frequently less than 1,200psi. In addition, the pipe is pre-tested at the factory then again field tested as a pipeline according to Public Service Company standards governed by DOT Code The specifications for the two pipeline sizes are: 0.375 wall thickness with a specified minimum yield strength of X-65 for the 24" pipeline; and 0.375 wall thickness with specified minimum yield strength of X-60 for the 20" pipeline. The X-60 and X-65 mean that the pipe configuration may begin to change at EXHIBIT a/ 6,000psi and 6,500psi respectively. The actual tensile strength or bursting pressure is considerably higher. Please call me at 294-8384 if I can be of further assistance. Sincerely, ( 3, ''2'' 'I` James M.

St. Vrain and fire protection measures at the plant. Listed below are issues identified from our meeting and also your letter to Weld County concerning this project. Fire Hydrant System. The existing fire hydrant system will be maintained. In addition, a new fire protection loop will be installed around the new equipment. Refer to the attached System Description for Fire Protection. Transformers. Fire walls will be installed between the major transformers and other equipment/structures . In addition, water deluge systems will also be installed on the major transformers. Cooling Tower. We are investigating the possible installation of additional fire protection on the cooling tower. Refurbishment of the tower will include the use of fire resistant material . Aux Electric and 480V Rooms. These rooms have detection and manual spray systems currently installed. We are not planning to modify these systems . Combustion Turbines . Each combustion turbine will be protected by a carbon dioxide fire protection system. Fire Watch Training. We have not yet determined how this training will be provided. EXHIBIT III Z3 Mr. Glenn Miller November 2, 1994 Page 2 We look forward to working with you as we near construction of this project and want to ensure that adequate fire protection exists at the plant site during construction and after project completion. Please call me at 303-329-1191 or Bob Gresham at 303- 329-1562 if we can answer any additional questions . Threl yours, Rick Thompson Associate Land Use Specialist Siting & Environmental Planning RT/eh Attachment cc: T. Hodges M. Block B. Gresham • • System Description for Fire Protection Function The Fire Protection System will provide appropriate methods of tire protection for the plant site, thereby minimizing the consequences of and damages from fire. The Fire Protection System conveys water from the existing Fire Water System to fire hydrants, hose stations, and fixed water suppression systems. The combustion turbine generator unit will be protected by a CO2 Fire Protection System. General Description The Fire Protection System consists of several dry chemical and carbon dioxide fire extinguishers, fire hydrants. interconnecting piping. valves. and accessories. Each combustion turbine is protected by an automatic carbon dioxide system furnished by the combustion turbine manufacturer. The Fire Protection System receives water from the existing t•..derground site fire protection water loop. Water from the existing fire protection loop is supplied to a common header (loop). The new fire protection loop surrounding the CTG/HRSG area provides water to the fire hydrants located around the facility. The loop also Ibranches to provide water to the deluge systems that protect the various electrical transformers. Building Number Ten Control Room will also be provided with fire detection/ protection systems. The electrical room of the Chemical/MCC Building will be provided with an independent ionization smoke detection system. Refer to Drawing 90110-700-M2005 for the Fire Protection System Flow Diagram. System Components I • Ionization Smoke Detection. • Fire Hydrants and Hydrant Houses. • CT CO2 Fire Protection System (By CT Manufacturer). • Transformer Deluge Systems (Including Valve Houses). • Dry Chemical Fire Extinguishers. • Carbon Dioxide Fire Extinguishers. • Fire Hose Cabinets. • Interconnecting Piping and Valving. 90110.700 i e$641:41 MEMORANDUM TO: Referral Agencies October 14, 1994 COLORADO From: Todd Hodges, Current Planner SUBJECT: Public Service Company of Colorado, Case USR-1063 This is additional information submitted by Public Service.
