There could also be up to 4 roundtrips per day of a truck and trailer (typically a 1 - ton or 1 % ton truck towing a flatbed). The construction term is estimated to be 7 to 9 months. Occasionally the facility may see a semi with a large track hoe or crane. The highest volume of traffic will be between 6:30 to 7:30 AM and 4:00 to 5:30 PM. During operations, it is anticipated that there will be approximately 2-5 roundtrip passenger cars and/or trucks per month. There could also be up to 4 roundtrips per month of a truck and trailer (typically a 1 - ton or 1 % ton truck towing a flatbed). The pump station is unmanned, so operational traffic will be limited to occasional maintenance activities. Construction and operation traffic will access the site from the south and west via Interstate 76, CO -71, and WCR 82. During construction and operation, the applicant anticipates that 80% of contractors and staff will access the site from the south and west from the Denver Area. 20% of travel may come from Cheyenne, Wyoming to the north. During construction, the highest volume traffic would occur between 6:30 and 7:30 a.m. and 4:00 and 5:30 as a result of employee commuter traffic.

The proposed pump station is approximately 0.5 mile from the nearest residence so visual impacts are mitigated by distance. Although visible from the County Road 82, the pump station is not out of character in rural Weld County where oil and gas uses are common and not regularly screened or landscaped. No water source is proposed, nor would well water be permitted to be used for purposes other than drinking. Decommissioning Plan ONEOK, Inc. (ONEOK) has no plans for future abandonment of the Stoneham Pump Station. Should abandonment be necessary, ONEOK will follow all applicable rules and regulations regarding decommissioning or abandonment in effect at that time, including those of the Colorado Oil and Gas Conservation Commission (COGCC) regulations regarding removal of equipment. Where practical, materials will be reused or recycled. Where required, materials to be disposed or recycled will be removed by a licensed contractor and transported to a location or facility that is permitted or otherwise authorized to accept such materials. ONEOK will comply with all COGCC regulations regarding site restoration. Noise Study The proposed pumps will be electrically powered and will be fully enclosed. Based on noise modeling of the equipment, the enclosed pumps will not exceed maximum permissible noise levels under the standards for oil and gas uses in the Residential/Agricultural/Rural zoning districts: daytime (55 db) and nighttime (50 db) at 350 feet from the noise source. Prior to operations, a noise measurement will be taken to confirm compliance. Should the measurement exceed maximum permissible levels, additional noise attenuation can be added to the pump enclosures to achieve compliance.

it is located within the Northwest'/ of Northeast 1/4 of section 13, township 7 North, 56 West There are no major dramageways or storm drainage facilities within or adjacent to the site 1.2 Description of Property 1.2.1 Existing Site The current Stoneham Pump Station site is approximately 5 67 acres covered by agncultural fields There are no affected wetland areas on or adjacent to the site 1.2.2 Existing Site Drainage The existing site contains a natural crest down the middle and roughly half of the site drains to the Northeast and half drains to the Northwest There's approximately 5 feet of overall elevation change from the high to low elevation points There is a high point in the middle of the site that directs flow to the northeast and southeast Currently, there is no storm drainage infrastructure on the site 1.2.3 Natural Resources Conservations Service (NRCS) Soil Survey Soil data was obtained from the NRCS website — Web Soil Survey Tool According to the NRCS report, the soils vary within the Platteville Terminal project site A summary of the NRCS Soil Report can be found in Appendix E The onsite soils are classified as Hydrologic Soil Group C thus, it exhibits slow infiltration rate when thoroughly wet 1.2.4 Proposed Land Use The Elk Creek Pipeline is part of a 700 -mile crude oil pipeline from Guernsey, WY to Cushing, OK that will provide shippers in the Rockies and Bakken access to destinations on the U S Gulf Coast This pump station will provide flow within Elk Creek Pipeline system Proposed additions to the site include (3) 5000 Horse Power Pumps, (2) Strainers, Control Valve, Power Distribution Center, electrical sub -station, and associated access drives The proposed development will include stormwater control features to meet Weld County Regulations 1.2.5 Wetlands There are no wetland areas located on or near the project site ONEOK, INC 1-1 Burns & McDonnell Stormwater Drainage Report Revision 1 General Location And Description 1.3 Permits Permits required for construction by the Weld County include a land disturbance permit (requires an Erosion Control Plan) and a building permit Additional required permits include a Colorado

Report Revision 1 Drainage Basins And Sub -Basins 2.0 DRAINAGE BASINS AND SUB -BASINS 2.1 Major Drainage Basins 2.1.1 Historic Basin A This major drainage basin generally slopes northeastward through Weld County It is located within the South Platte River basin The basin outlets into the South Platte River 2.2 Minor Drainage Basins A Drainage Basin Map showing the extents of the offsite drainage basins, post development drainage basins and locations of drainage features within the project site has been included in Appendix A All hydrologic calculations can be found in Appendix C, which include weighted C calculations, and peak runoff prediction for each basin All hydraulic calculations can be found in Appendix D, which include swale sizing, culvert sizing, and detention pond sizing 2.2.1 Historic Basin A Historic Basin A is a 2 55 -acre basin that runs along most of the western side of the site The basin is made up of agricultural fields and has an imperviousness of 2 0% The basin is composed of soil type C The general routing for the runoff from this basin flows to the northeast and then continues offsite The runoff from this basin flows through the site and will be needed to be accounted for in the spillway calculations for the detention pond 2.2.2 Historic Basin B Historic Basin B a 3 l2 -acre basin that runs along the eastern side of the site The basin is made up of agncultural fields and has an imperviousness of 2 0% The basin has soil types that are hydrologic soil group C The general routing for the runoff from this basin flows northeast and then continues offsite The runoff from this offsite basin flows through the site and will be needed to be accounted for in the spillway calculations for the southern detention pond 2.2.3 Developed Basin C The 5 67 -acre developed basin encompasses all of the site Soil types within the basin are hydrologic soil group C The existing grades of this basin conveys runoff to the northeast and northwest corners of the site, which then flows offsite The discharges for Histonc Basin A and Historic Basin B were summed up to meet detention basin design requirements When the proposed improvements are built, the developed basin will be aggregate Due to the proposed improvements the imperviousness will increase to 25%, causing the 10 -year flow to increase to 12 02 cfs, and the 100 -year flow to 21 09cfs In order to account ONEOK, INC 2-1 Burns & McDonnell Stormwater Drainage Report Revision 1 Drainage Basins And Sub -Basins for the additional runoff from the increased imperviousness, a detention pond will be implemented on site Table 2-1.

3.0 DRAINAGE DESIGN CRITERIA 3.1 Regulations The design criteria for the proposed drainage system for the Stoneham Pump Station project is in accordance with Weld County's Weld County Engineering Construction Gurdehnes document and the Urban Drainage and Flood Control District's Urban Storm Drainage Criteria Manual (USDCM) 3.2 Hydrologic Criteria The proposed drainage facilities were analyzed using a 10 -year recurrence interval design storm (1 67 inches/hour) for the minor event and a 100 -year interval design storm (2 93 inches/hour) for the major event The design storms were collected from the NOAA Precipitation Frequency Data Server (PFDS) The rational method in the UD-Rational vl 02a spreadsheet were used to calculate runoff for all parts of the project area This spreadsheet was downloaded off the Weld County website This method was utilized because the overall drainage area is less than 90 acres The detailed results of the hydrologic computation are presented in Appendix C 3.3 Hydraulic Criteria Hydraulic analyses were performed to size and evaluate the performance of the detention pond with outlet structure, drainage swale, and culverts The site was designed with the assumption of being classified as non -urbanizing This would require the detention ponds to detain the 1 -hour 100 -year storm event and to have a total release rate, for this storm event, equal to the 1 -hour 10 -year historic release rate To calculate the detention ponds size and outlet controls the UDFCD "UD-Detention v2 35" spreadsheet was used Detention pond volume calculated in "UD-Detention v2 35" was not equal to AutoCAD Civil 3D design pond volume As a result the design detention pond length and width differ from calculated detention pond length and width Design detention pond volumes and elevations meet those calculated shown in "UD-Detention v2 35" The spreadsheet was downloaded off the Weld County website The detailed results of the hydraulic computation are presented in Appendix D 3.3.1 Detention Ponds The capacity for the detention pond is designed to fully detain the WQCV and 1 -hour 100 -year storm event for the basin that is flowing into the pond The spillway and outlet structure have been designed to safely discharge on -site flow A concrete outlet structure and culvert was designed for the detention pond and was sized using the "UD-Detention v2 35" spreadsheet The outlet structure is designed to release the WQCV in a 40 -hour time span and the 99% of all runoff from each storm event within a 120 -hour time span The pond has a rip rap armored spillway that is designed to allow for a 6 inch flow depth and 6 ONEOK, INC 3-1 Bums & McDonnell Stormwater Drainage Report Revision 1 Drainage Design Cntena inches of freeboard during a storm event that surpasses the 100 -year storm The spillway crest length is 15 17 feet and has an invert 12 inches below the top of the pond The release rate for the detention pond is controlled by a concrete outlet structure with a 12 inch culvert that has a rectangular restnctor plate that starts 9 inches above the invert of the pipe The outlet structure is designed to have a release rate equal to the 1 -hour 10 -year historic runoff of the developed basin (3 67 cfs) during a 1 -hour 100 -year storm event After releasing from the culvert, runoff will pass through the nprap protected outlet and then it will discharge off site 3.4 Water Quality Management To verify compliance with the County's criteria and promote enhanced water quality in stormwater leaving the site, Best Management Practices (BMP's) were utilized The detention pond captures, detains, and releases the WQCV within a time period of 40 hours within the respective basins 3.5 Erosion and Sedimentation Control Several non-structural BMP's will be incorporated throughout construction including phasing and completing land disturbing activities, minimizing disturbed areas, roughening disturbed areas, and reseeding or final stabilization promptly after land disturbance Structural BMP's to be used on the site include sediment control logs, nprap inlet/outlet protection, vehicle tracking control, concrete washout area, and a stabilized staging area Silt fencing will be installed along the perimeters of the site, as well as around any temporary stockpiling locations utilized by the contractor All slopes greater than or equal to 4 1 (H V) will be stabilized with erosion control blankets Sediment control logs will also be utilized near storm inlets and locations of heavy flow volumes, to aid in reducing runoff velocity and to allow suspended particulate to settle out Riprap protection will be installed at culvert outlets and pond spillways Vehicle tracking control will be installed at the construction site entrance, as well as a concrete washout All construction traffic will have limited access to the site, through the construction entrance only A stabilized staging area will be installed to reduce erosion for staging material storage areas with high construction traffic Inlet protection will be installed at all culvert, storm sewer, and outlet structures to improve water quality before releasing runoff downstream The site will remain in a roughened condition during construction and will be promptly graveled after land disturbing activities have been completed These structural BMPs can be seen in the grading control plan, provided in Appendix B ONEOK, INC 3-2 Burns & McDonnell Stormwater Drainage Report Revision 1 Conclusions 4.0 CONCLUSIONS 4.1 Compliance with Standards The design of the proposed drainage system for the Stoneham Pump Station project complies with the adopted drainage cntena of Weld County and the standards of the Urban Drainage and Flood Control District The design cntena for the proposed drainage system are in accordance with the Weld County Engineering Construction Guidelines and the Urban Drainage and Flood Control Distnct`s Urban Storm Drainage Criteria Manual (USDCM) 4.2 Drainage Concept Summary The proposed system design will adequately protect public health, safety, and general welfare and have no adverse impacts on public nghts-of-way or offsite properties The proposed drainage facilities will improve drainage conditions after construction of the Stoneham Pump Station project and provide water quality benefits prior to stonnwater

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A, B, C. and D) and three dual classes (A/D. B/D. and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table. soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D. B/D, or C/D), the first letter is for drained areas and the second is for undrained areas.

Report Revision 0 General Location And Description 1 0 GENERAL LOCATION AND DESCRIPTION 1.1 Site Location The Stoneham Pump Station is located on the south side of Weld County Road (WCR) 82, 0 42 miles west of WCR 157 More accurately, it is located within the Northwest IA of Northeast IA of section 13, township 7 North, 56 West There are no major drainageways or storm drainage facilities within or adjacent to the site 1.2 Description of Property 1 2.1 Existing Site The current Stoneham Pump Station site is approximately 5 67 acres covered by agricultural fields There are no affected wetland areas on or adjacent to the site 1.2.2 Existing Site Drainage The existing site contains a natural crest down the middle and roughly half of the site drains to the Northeast and half drains to the Northwest There's approximately 5 feet of overall elevation change from the high to low elevation points There is a high point in the middle of the site that directs flow to the northeast and southeast Currently, there is no storm drainage infrastructure on the site 1.2.3 Natural Resources Conservations Service (NRCS) Soil Survey Soil data was obtained from the NRCS website — Web Soil Survey Tool According to the NRCS report, the soils vary within the Platteville Terminal project site A summary of the NRCS Soil Report can be found in Appendix E The onsite soils are classified as Hydrologic Soil Group C thus, it exhibits slow infiltration rate when thoroughly wet 1.2.4 Proposed Land Use The Elk Creek Pipeline is part of a 700 -mile crude oil pipeline from Guernsey, WY to Cushing, OK that will provide shippers in the Rockies and Bakken access to destinations on the U S Gulf Coast This pump station will provide flow within Elk Creek Pipeline system Proposed additions to the site include (3) 5000 Horse Power Pumps, (2) Strainers, Control Valve, Power Distribution Center, electrical sub -station, and associated access drives The proposed development will include stormwater control features to meet Weld County Regulations 1.2.5 Wetlands There are no wetland areas located on or near the project site ONEOK, INC 1-1 Burns & McDonnell Stormwater Drainage Report Revision 0 General Location And Description 13 Permits Permits required for construction by the Weld County include a land disturbance permit (requires an Erosion Control Plan) and a building permit Additional required permits include a Colorado Department of Public Health & Safety (CDPHE) Construction Stormwater Discharge Permit, USR Permit, Access permit, and Weld County Grading Permit ONEOK, INC 1-2 Burns & McDonnell Stormwater Drainage Report Revision 0 Drainage Basins And Sub -Basins 2.0 DRAINAGE BASINS AND SUB -BASINS 2 1 Major Drainage Basins 2 1 1 Historic Basin A This major drainage basin generally slopes northeastward through Weld County It is located within the South Platte River basin The basin outlets into the South Platte River 2.2 Minor Drainage Basins A Drainage Basin Map showing the extents of the offsite drainage basins, post development drainage basins and locations of drainage features within the project site has been included in Appendix A All hydrologic calculations can be found in Appendix C, which include weighted C calculations, and peak runoff prediction for each basin All hydraulic calculations can be found in Appendix D, which include swale sizing, culvert sizing, and detention pond sizing 2.2.1 Historic Basin A Historic Basin A is a 2 55 -acre basin that runs along most of the western side of the site The basin is made up of agricultural fields and has an imperviousness of 2 0% The basin is composed of soil type C The general routing for the runoff from this basin flows to the northeast and then continues offsite The runoff from this basin flows through the site and will be needed to be accounted for in the spillway calculations for the detention pond 2 2.2 Historic Basin B Historic Basin B a 3 12 -acre basin that runs along the eastern side of the site The basin is made up of agricultural fields and has an imperviousness of 2 0% The basin has soil types that are hydrologic soil group C The general routing for the runoff from this basin flows northeast and then continues offsite The runoff from this offsite basin flows through the site and will be needed to be accounted for in the spillway calculations for the southern detention pond 2.2.3 Developed Basin C The 5 67 -acre developed basin encompasses all of the site Soil types within the basin are hydrologic soil group C The existing grades of this basin conveys runoff to the northeast and northwest corners of the site, which then flows offsite The discharges for Historic Basin A and Historic Basin B were summed up to meet detention basin design requirements When the proposed improvements are built, the developed basin will be aggregate Due to the proposed improvements the imperviousness will increase to 25%, causing the 10 -year flow to increase to 12 02 cfs, and the 100 -year flow to 21 09cfs In order to account ONEOK, INC 2-1 Burns & McDonnell Stormwater Drainage Report Revision 0 Drainage Basins And Sub -Basins for the additional runoff from the increased imperviousness, a detention pond will be implemented on site Table 2-1: Minor Drainage Basins Summary Minor Drainage Basin Existing Total Impery (%) Proposed Total Impery (%)

ONEOK, INC 2-2 Burns & McDonnell Stormwater Drainage Report Revision 0 Drainage Design Cntena 3 0 DRAINAGE DESIGN CRITERIA 3.1 Regulations The design cntena for the proposed drainage system for the Stoneham Pump Station project is in accordance with Weld County's Weld County Engineering Construction Guidelines document and the Urban Drainage and Flood Control District's Urban Storm Drainage Criteria Manual (USDCM) 3.2 Hydrologic Criteria The proposed drainage facilities were analyzed usmg a 10 -year recurrence interval design storm (1 67 inches/hour) for the minor event and a 100 -year interval design storm (2 93 inches/hour) for the major event The design storms were collected from the NOAA Precipitation Frequency Data Server (PFDS) The rational method in the UD-Rational vl 02a spreadsheet were used to calculate runoff for all parts of the project area This spreadsheet was downloaded off the Weld County website This method was utilized because the overall drainage area is less than 90 acres The detailed results of the hydrologic computation are presented in Appendix C 3.3 Hydraulic Criteria Hydraulic analyses were performed to size and evaluate the performance of the detention pond with outlet structure, drainage swale, and culverts The site was designed with the assumption of being classified as non -urbanizing This would require the detention ponds to detain the 1 -hour 100 -year storm event and to have a total release rate, for this storm event, equal to the 1 -hour 10 -year historic release rate To calculate the detention ponds size and outlet controls the UDFCD "UD-Detention v2 35" spreadsheet was used Detention pond volume calculated in "UD-Detention v2 35" was not equal to AutoCAD Civil 3D design pond volume As a result the design detention pond length and width differ from calculated detention pond length and width Design detention pond volumes and elevations meet those calculated shown in "UD-Detention v2 35" The spreadsheet was downloaded off the Weld County website The detailed results of the hydraulic computation are presented in Appendix D 3.3 1 Detention Ponds The capacity for the detention pond is designed to fully detain the WQCV and 1 -hour 100 -year storm event for the basin that is flowing into the pond The spillway and outlet structure have been designed to safely discharge on -site flow A concrete outlet structure and culvert was designed for the detention pond and was sized using the "UD-Detention v2 35" spreadsheet The outlet structure is designed to release the WQCV in a 40 -hour time span and the 99% of all runoff from each storm event within a 120 -hour time span The pond has a np rap armored spillway that is designed to allow for a 6 inch flow depth and 6 ONEOK, INC 4-1 Burns & McDonnell Stormwater Drainage Report Revision 0 Drainage Design Cntena inches of freeboard dunng a storm event that surpasses the 100 -year storm The spillway crest length is 15 17 feet and has an invert 12 inches below the top of the pond The release rate for the detention pond is controlled by a concrete outlet structure with a 12 inch culvert that has a rectangular restnctor plate that starts 9 inches above the invert of the pipe The outlet structure is designed to have a release rate equal to the 1 -hour 10 -year histonc runoff of the developed basin (3 67 cfs) during a 1 -hour 100 -year storm event After releasing from the culvert, runoff will pass through the nprap protected outlet and then it will discharge off site 3 4 Water Quality Management To verify compliance with the County's cntena and promote enhanced water quality in stormwater leaving the site, Best Management Practices (BMP's) were utilized The detention pond captures, detains, and releases the WQCV within a time period of 40 hours within the respective basins 3.5 Erosion and Sedimentation Control Several non-structural BMP's will be incorporated throughout construction including phasing and completing land disturbing activities, minimizing disturbed areas, roughening disturbed areas, and reseeding or final stabilization promptly after land disturbance Structural BMP's to be used on the site include sediment control logs, nprap inlet/outlet protection, vehicle tracking control, concrete washout area, and a stabilized staging area Silt fencing will be installed along the penmeters of the site, as well as around any temporary stockpiling locations utilized by the contractor All slopes greater than or equal to 4 1 (H V) will be stabilized with erosion control blankets Sediment control logs will also be utilized near storm inlets and locations of heavy flow volumes, to aid in reducing runoff velocity and to allow suspended particulate to settle out Riprap protection will be installed at culvert outlets and pond spillways Vehicle tracking control will be installed at the construction site entrance, as well as a concrete washout All construction traffic will have limited access to the site, through the construction entrance only A stabilized staging area will be installed to reduce erosion for staging material storage areas with high construction traffic Inlet protection will be installed at all culvert, storm sewer, and outlet structures to improve water quality before releasing runoff downstream The site will remain in a roughened condition during construction and will be promptly graveled after land disturbing activities have been completed These structural BMPs can be seen in the grading control plan, provided in Appendix B ONEOK, INC 4-1 Burns & McDonnell Stormwater Drainage Report Revision 0 Conclusions 4 0 CONCLUSIONS 4.1 Compliance with Standards The design of the proposed drainage system for the Stoneham Pump Station project complies with the adopted drainage criteria of Weld County and the standards of the Urban Drainage and Flood Control District The design criteria for the proposed drainage system are to accordance with the Weld County Engmeermg Construction Guidelines and the Urban Drainage and Flood Control District's Urban Storm Dramage Crtterta Manual (USDCM) 4.2 Drainage Concept Summary The proposed system design will adequately protect public health, safety, and general welfare and have no adverse impacts on public rights -of -way or offsite properties The proposed drainage facilities will improve drainage conditions after construction of the Stoneham Pump Station project and provide water quality benefits prior to stormwater leaving the site ONEOK, INC 4-1 Burns & McDonnell Stormwater Drainage Report Revision 0

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A. B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas.

Scope The Natural Gas Liquids (NGL) Operations and Maintenance Manual (O&M Manual) is a Level 3 governance document that applies to NGL facilities operated by ONEOK and its subsidiaries that are subject to the jurisdiction and regulations of the Department of Transportation (DOT). The O&M Manual contains procedures written in accordance with the requirements of the Pipeline and Hazardous Materials Safety Administration (PHMSA) 49 CFR Part 195 and other appropriate codes and standards and assigns responsibility for the operation and maintenance of such facilitates. 49 CFR Part 195 applies to pipeline facilities and the transportation of hazardous liquids associated with those pipeline facilities in or affecting interstate or foreign commerce. Procedures that do not pertain to hazardous liquids handling, related pipeline facilities and underground storage facilities are not included in this manual but are referenced when appropriate. 49 CFR 195, Subpart F states that each operator shall: "Establish a written operating and maintenance plan meeting the requirements of this part and keep records necessary to administer the plan. Each operator shall include the following in their operating and maintenance plan: • Instructions for employees performing operating and maintenance procedures during normal operation, abnormal operations, and emergencies, • Specific programs relating to pipeline and storage facilities presenting the greatest hazard to public safety. either in an emergency or because of extraordinary construction or maintenance requirements. • Specific instructions enabling personnel who perform operation and maintenance activities to recognize conditions that may be safety -related conditions." • This manual shall be reviewed once each calendar year not to exceed 15 months. 1.1 Environment Safety and Health (ESH) Policy ONEOK will manage all operations in a manner that protects the safety and health of employees, customers, contractors, and the public and protects the environment, while fully complying with applicable laws and regulations. ONEOK will continually improve environmental. health, and safety performance by proactively evaluating its business and operations and implementing management systems to reduce the number and severity of accidents. toward a goal of zero Accidents. Orientation is recommended for all Contractors, ONEOK Employees, and visitors who will provide services on ONEOK operating facilities and ROW. The orientation will be the presentation of the ESH Contractor Orientation Handbook. Note: Reporting may be done by other means, including using electronic database forms, as long as the required information is reported.

F Owner: Vice President Natural Gas Liquids Security of Pipeline ONEOK will provide protection from vandalism and unauthorized entry for each pumping station, Facilities breakout tank area, or other exposed pipeline facilities. Block valve locations that are readily accessible to the general public shall be fenced, unless determined otherwise by the Operations Supervisor. The geographical location of the valves will aide in determining if a chain link fence is required. Securing pipeline facilities will not only keep unauthorized people and livestock out of the pipeline facility but may also deter saboteurs or vandals. When fencing is utilized to secure a facility, • New perimeter fences shall be installed to insure there are no large gaps or holes that would allow unpermitted entry • Determine the appropriate fence height for the area being secured. Six-foot high chain - link fence is recommended. • Entrances such as gates shall be secured to restrict entry by unauthorized personnel • Fences will be monitored during routine operations and properly maintained 195.436 Tank Farm Security 195.436 Block Valves Security 195.436 Pump Stations Security 195.436 Rectifiers Security 195.436 Scraper Trap Facilities Security 195.436 Jurisdictional pipeline facilities, such as breakout storage facilities on pipelines, shall be secured by installing a fence around each facility as appropriate for the area. Normally, this includes a fence around the perimeter of the facility or around the aboveground components of the pipeline facility not otherwise secured. If fencing is impractical, tanks may be secured by fencing the stairway landing to deny access to the stairway. The stairway fencing shall be locked at all times, except when being used by an employee. If this method of security is used. all tank valves shall also be fitted with locked devices and kept locked to prevent their opening or closing. All gates providing access to the facility shall be equipped with locking devices and shall be kept locked when the facility is unmanned. All mainline block valves, and any other valves. located in an unsecured area that have the potential of over -pressuring or causing a release of the pipeline liquid if opened or closed unexpectedly shall be fitted with a locking device and kept locked in the desired position. Pump stations shall be secured in the same manner as tank farms. Besides the general security provided by fencing, the additional security of locking is recommended for things such as doors to electrical switchgear buildings, offices, transformers, and other electrical equipment carrying voltages greater than 220 volts. Rectifiers along the pipeline shall be installed in an enclosure equipped for locking and shall be kept locked unless work is being performed. Rectifiers inside secured facilities are not required to be locked. Scraper traps will be secured by fencing the trap area with a security fence appropriate for the area or an appropriate locking device. WARNING: The content of this document is considered PRIVATE.

The cathodic protection must be in operation not later than one (1) year after the pipeline is constructed. relocated, replaced. converted to service. or otherwise changed. Corrosion personnel are responsible for maintaining an adequate cathodic protection system for the prevention of corrosion on pipeline systems. ONEOK cathodic protection supervisors are responsible for maintaining a thorough knowledge of corrosion control procedures established in this Manual. for which they are also responsible for ensuring compliance. Cathodic protection may be provided by impressed current systems or galvanic anode systems. If external or internal corrosion exists to a degree where leakage might result.. the pipe must be repaired or replaced, or the operating pressure must be reduced commensurate with the strength of the pipe, based on actual remaining wall thickness. This can be determined using procedures found in ASME B31 G, AGA Battelle Modified Criterion, RSTRENG. or other acceptable criteria. To monitor the effectiveness of the cathodic protection system and to comply with regulatory requirements, perform the surveys and prepare reports noted in this Section. Cathodic protection for NGL-operated pipelines shall comply with one or more of the applicable criteria and other considerations for cathodic protection contained in Sections 6.2 and 6.3 of NACE Standard SP 0169-2007 (incorporated by reference). NGL operated pipelines shall meet any of the criteria set forth in NGLdot3.0550, Corrosion Control Manual. Section 3.2 — CP Criteria in the Corrosion Control Manual lists the following three cathodic protection criteria: 1. Negative 850 mV with CP applied and IR considered: 2. Negative Polarized Potential of at least 850 mV; and 3. 100 mV Cathodic Polarization. Any of these criteria can be applied to any test point at any time. Survey documents or subsequent remedial action must indicate that one of these criteria is met at each test point. If the pipeline is in a High Voltage A/C Power Corridor or paralleling within 500 feet of a HVAC line, A/C voltage readings must be taken. If deemed necessary by the corrosion specialist or supervisor, external A/C monitoring coupons may be required. When tests or inspections indicate that cathodic protection systems are no longer achieving the established criteria, the following procedures will be implemented. This includes but is not limited to: below criteria pipe -to -soil potentials and rectifier output deficiencies. 1. After discovery, notify the Cathodic Protection Supervisor or designee. 2. The Cathodic Protection Supervisor or designee shall review the evaluation and initiate appropriate remedial action. Remedial action shall be completed in accordance with NGLdot3.0550.

Abnormal Operating Conditions (AOC) An Abnormal Operation Condition (AOC) is defined as a condition occurring at ONEOK's pipeline facilities which results in a deviation from normal operations that could cause a hazard to persons or property, or when operating design limits have been exceeded. ADCs, while not intended or expected, are not considered emergency conditions. However, if an AOC is ignored and not corrected, it could result in an emergency. If an AOC is observed in the field and cannot be corrected, the observing employee should notify their supervisor and the Pipeline Control Center (PCC). Ensure the area is safe prior to initiating notification. If required, the employee may assist with corrective measures or investigation. For ADCs observed by the PCC, evaluate the condition to determine the appropriated action that may include field or supervisor notification. The procedures for PCC are located in the CRM Plan Abnormal Operating Conditions on SharePoint Control Room Management under Natural Gas Liquids PCC. In an emergency situation, refer to Section 2.0 of this Manual and the Section 5.2.2.3 of the Pipeline Controller Emergency Operating Conditions Roles and Responsibilities of the Control Room Management (CRM).

These procedures cover the handling of events that are potentially hazardous to people or property. but that are corrected before an emergency situation develops. For more details refer to the CRM Abnormal Operating Conditions located on the Control Room Management under Natural Gas Liquids PCC SharePoint site. The following general guidelines apply when responding to an AOC. Upon arriving at the site, personnel should determine if there is an immediate danger to themselves or to the public. Personnel observing a condition that is potentially hazardous shall take action to correct the condition provided performing the required action does not endanger the personnel. When safe, the personnel shall: • Return the abnormal condition to normal condition. • Notify the Pipeline Control Center of the action taken. • Monitor the return to normal operation. • Document changes made to correct the AOC. To provide assistance as required, field personnel will be accessible as follows: During normal work hours. the PCC may request assistance with investigating and/or correcting an abnormal condition by notifying field operations personnel to determine their availability as necessary. A callout list is made available to the PCC, identifying personnel to notify if assistance is required during unscheduled work periods. Phone numbers for the personnel will be provided on the callout list or can be located at ONEOK Online. Personnel identified for callout duty will notify the PCC of their whereabouts and how to be reached if the phone number changes from what is on the callout list. If the individual on callout duty cannot be reached, the PCC will attempt to reach other personnel in the vicinity. After the AOC has been corrected, critical locations in the system should be checked for variations from normal operation to determine continued integrity and safe operation. After the required actions are completed to correct an abnormal operation or abnormal operating condition, the PCC shall be notified that the affected equipment or pipeline facility is available for service. Once the equipment or pipeline facility is returned to the PCC's control; field personnel shall be available to observe the equipment or pipeline facility in operation until both field personnel and the PCC are satisfied that conditions are normal. Each time the system is shut down, restarted, or altered for failures, replacements, repairs, or natural disasters. pressure and flow rate must be monitored until the system is operating normally. If the system is not monitored through SCADA, personnel must be in attendance to ensure pressures remain below MOP. All AOCs identified by the PCC shall be logged in Maxlog on the current active shift under the log tab as an AOC log type. The AOC log entry should include the response to the AOC and any corrective actions taken at the time of the event. AOCs identified by field personnel are documented in Enablon or PCC will document in Maxlog. Near Misses identified by field personnel can be documented in Enablon.

Manual Subject: Natural Gas Liquids Operations and Maintenance Manual Document No.: PRC1400.000 Section 5 Date Revised: 07/01/20 Rev: 19 � � ONEOK • Owner: Vice President Natural Gas Liquids Educating the Public Contact/ Contractor Documentation General Policy - Nearby Construction ONEOK has an established continuing education program that enables the Affected Public, Local Officials, Landowners, and Excavators to recognize and report a pipeline emergency. The Public Awareness program must be comprehensive and reach all areas through which NGL transports petroleum products. The ONEOK Public Awareness Representative or designee determines the method(s) of conducting a pipeline safety educational program that enables the stakeholders residing, responding or digging in close proximity to the pipeline right-of-way to recognize, respond, and report an emergency, ONEOK's stakeholders include: • The Affected Public • Excavators • Public Officials, and • Contractor / Excavators The Public Awareness program must be conducted in English and if other languages are commonly used within the area, consideration should be made to develop material in the second language to ensure the message is understood. When making contact with stakeholders ONEOK shall educate stakeholders on safe digging practices, how to recognize a pipeline leak and how to respond to an emergency involving ONEOK's pipeline facilities. The ONEOK Public Awareness representative or designee shall be responsible for maintaining current address lists of the affected public, public officials, excavators and emergency responders. The ONEOK Public Awareness Representative shall maintain State Pipeline Associations, supplemental activities and any associated contact and interactions with Stakeholders. As a general policy, any construction near or within an ONEOK right-of-way will be investigated to determine the limits of the project and if ONEOK pipeline facilities are within those limits. This includes, but is not limited to: • Foreign pipelines: • Petroleum, water, or other well -drilling activities; • Electric cables or telephone lines: • Drilling holes for poles, posts, or anchors; • Directional drilling and boring; and • Any other activity requiring excavation, such as building foundations, terracing, etc. The primary intent of this investigation is safety. By preventing damage to the pipeline, the danger of injuring personnel or property from an unintentional escape of petroleum products or crude oil is eliminated. When ONEOK pipeline facilities are within the limits of a construction project, or near enough that construction activity or equipment may encroach on ONEOK right-of-way, every ONEOK line will be located and sufficiently marked to indicate its position within or near the construction site. If blasting is anticipated, the required blasting information shall be obtained. (See Blasting Section in this document) and communicate it to the ONEOK Business Engineer or another appropriate supervisor for a decision as to whether or not to allow such blasting. The same policy applies when a new ONEOK pipeline crosses an existing ONEOK pipeline or foreign structure. as well as during maintenance or replacement of ONEOK pipeline facilities by ONEOK employees or contractors.

If the notice is cleared in the office by the One -Call Technician (OCT), the status shall be updated in the ticket tracking program by the OCT. All notices dispatched to field technicians for response shall be updated the ticket tracking program by the field technician. ONEOK will respond to these notifications pursuant to. Excavation Notification and Response Document. When an ONEOK pipeline facility will be crossed or encroached upon by a foreign structure, follow the Foreign Structure Crossing Procedure in this manual. Line locating shall be performed in accordance with the qualification requirements of ONEOK's Operator Qualification Plan (2.000.2100) and the Level 2 Line Locating Standard OKSdot2.0001, Care must be taken to ensure the correct route is determined. When locating pipelines, use probing or excavation to verify actual location of pipeline. Pipelines can be located by: • The pipeline markers present; • Change in vegetation; • Metal detectors; or • Probing and excavating. ONEOK employees must use stakes, signs, or flags to identify the location of the pipeline at intervals determined sufficient for the particular situation. In locations where paving or terrain do not permit standard markers, use paint to mark the line. Markings should follow State Damage Prevention laws. And may utilize the CGA best practices for line locating as an additional resource for marking pipelines. The Best Practices Guide may be found at https://commongroundalliance.com/best-practices-guide. If blasting is anticipated during the excavation project, notify the ONEOK Business Engineer or another appropriate supervisor for approval. The following blasting information is required: • Configuration of the explosive charges (point, line, or grid):. • Number of charges: • Spacing between charges; • Type of charge and weight; • Distance between pipeline and nearest charge for each pipeline; • Angle between pipeline and explosive line or grid; • If grid, number of rows and number of charges per row; and • Pipe description of each pipeline. After blasting is completed, an inspection must include leakage surveys. Note: If necessary, an outside consultant can be used to determine the proper blasting procedure.

Manual Subject: Natural Gas Liquids Operations and Maintenance Manual Document No.: PRC1400.000 Section Appendix C Date Revised: 07/01'20 Rev. 19 z = ONEOK Owner: Vice President Natural Gas Liquids Appendix C: Advisory Bulletin - Damage to Pipeline Facilities Caused by Flooding Advisory (ADB-2015-10): Severe flooding can adversely affect the safe operation of a pipeline. Operators need to direct their resources in a manner that will enable them to determine and mitigate the potential effects of flooding on their pipeline systems in accordance with applicable regulations. Operators are urged to take the following actions to prevent and mitigate damage to pipeline facilities and ensure public and environmental safety in areas affected by flooding: 1. Utilize experts in river flow, such as hydrologists or fluvial geomorphologists, to evaluate a river's potential for scour or channel migration at each pipeline river crossing. 2. Evaluate each pipeline crossing a river to determine the pipeline's installation method and determine if that method (and the pipeline's current condition) is sufficient to withstand the risks posed by anticipated flood conditions, river scour, or river channel migration. In areas prone to these conditions and risks, consider installing pipelines using horizontal directional drilling to help place pipelines below elevations of maximum scour and outside the limits of lateral channel migration. 3. Determine the maximum flow or flooding conditions at rivers where pipeline integrity is at risk in the event of flooding (e.g., where scour can occur) and have contingency plans to shut down and isolate those pipelines when such conditions occur. 4. Evaluate the accessibility of pipeline facilities and components that may be in jeopardy, such as valve settings, which are needed to isolate water crossings or other sections of pipelines. 5. Extend regulator vents and relief stacks above the level of anticipated flooding as appropriate. 6. Coordinate with emergency and spill responders on pipeline locations, crossing conditions, and the commodities transported. Provide maps and other relevant information to such responders so they can develop appropriate response strategies. 7. Coordinate with other pipeline operators in flood areas and establish emergency response centers to act as a liaison for pipeline problems and solutions. 8. Deploy personnel so that they will be in position to shut down, isolate, contain, or perform any other emergency action on an affected pipeline. 9. Determine if facilities that are normally above ground (e.g., valves, regulators, relief sets, etc.) have become submerged and are in danger of being struck by vessels or debris and, if possible, mark such facilities with U.S. Coast Guard approval and an appropriate buoy. 10. Perform frequent patrols, including appropriate overflights, to evaluate right-of-way conditions at water crossings during flooding and after waters subside. Report any flooding, either localized or systemic, to integrity staff to determine if pipeline crossings may have been damaged or would be in imminent jeopardy of future flooding. 11. Have open communications with local and state officials to address concerns regarding observed pipeline exposures. localized flooding, ice dams. debris dams, and extensive bank erosion that may affect the integrity of pipeline crossings. 12. Following floods, and when safe river access is first available, determine if flooding has exposed or undermined pipelines because of new river channel profiles. This is best done by a depth of cover survey. 13. Where appropriate, surveys of underwater pipe should include the use of visual inspection by divers or instrumented detection. Pipelines in recently flooded lands adjacent to rivers should also be evaluated to determine the remaining depth of cover. Information gathered by these surveys should be shared with affected landowners. Agricultural agencies may help inform farmers of potential hazards from reduced cover over pipelines. 14. Ensure that line markers are still in place or are replaced in a timely manner. Notify contractors, highway departments, and others involved in post -flood restoration activities of the presence of pipelines and the risks posed by reduced cover. If pipeline has suffered damage or is shut-in as a precautionary measure due to flooding, the operator should advise the appropriate PHMSA regional office or state pipeline safety authority before returning the line to service, increasing its operating pressure, or otherwise changing its operating status. Furthermore, reporting a Safety -Related Condition as prescribed in 49 CFR 191.23 and 195.55 may also be required. WARNING: The content of this document is considered PRIVATE.

Manual Subject: Natural Gas Liquids Operations and Maintenance Manual Document No.: PRC1400.000 Section Appendix D Date Revised: 07/01/20 Rev. 19 ONEOK Owner: Vice President Natural Gas Liquids Appendix D: Advisory Bulletin - Damage to Pipeline Facilities Caused by Hurricanes Advisory Bulletin (ADB-2015-02): All owners and operators of gas and hazardous liquid pipelines are reminded that pipeline safety problems can occur from the passage of hurricanes. Pipeline operators are urged to take the following actions to ensure pipeline safety: 1. Identify persons who normally engage in shallow -water commercial fishing, shrimping, and other marine vessel operations and caution them that underwater offshore pipelines may be exposed or constitute a hazard to navigation. Marine vessels operating in water depths comparable to a vessel's draft or operating bottom dragging equipment can be damaged and their crews endangered by an encounter with an underwater pipeline. 2. Identify and caution marine vessel operators in offshore shipping lanes and other offshore areas that deploying fishing nets or anchors and conducting dredging operations may damage underwater pipelines, their vessels, and endanger their crews. 3. After a disruption, operators need to bring offshore and inland transmission facilities back online, check for structural damage to piping, valves, emergency shutdown systems, risers and supporting systems. Aerial inspections of pipeline routes should be conducted to check for leaks in the transmission systems. In areas where floating and jack -up rigs have moved and their path could have been over the pipelines, review possible routes and check for sub -sea pipeline damage where required. 4. Operators should take action to minimize and mitigate damages caused by flooding to gas distribution systems, including the prevention of overpressure of low pressure and high pressure distribution systems. PHMSA would appreciate receiving information about any damage to pipeline facilities caused by hurricanes. The federal pipeline safety regulations require that operators report certain incidents and accidents to PHMSA by specific methods. Damage not reported by these methods may be reported to David Lehman, Director for Emergency Support and Security. 202-366-4439 or by email at PHMSA.OPA90@dot.gov.
