Appendix D: Fire Apparatus Access Roads The provisions contained in this appendix are not mandatory unless specifically referenced in the adopting ordinance. General Comments Fire apparatus access is absolutely essential to suc- cessful fire fighting and rescue operations. Fire depart- ment vehicles vary widely in size and operational needs and must be able to maneuver into position to properly undertake their fire -fighting activities. The needs of each jurisdiction will therefore vary with the equipment used. Needs assessment should also include consideration of mutual -aid companies that may respond from outside the jurisdiction. Access roads must be designed to pro- vide the fire department with the required access to all structures on a site. Purpose This appendix contains more detailed elements for use with the basic access requirements found in Section 503. Section 503 gives some minimum criteria, such as a maximum distance of 150 feet (45 720 mm) and a minimum width of 20 feet (6090 mm), but in many cases Section 503 does not state specific criteria. For exam- ple, what specific load should a fire apparatus access road be able to carry and what specific grade is allowed? Section 503 cannot go into this level of detail because the needs vary widely from one jurisdiction to another. This appendix, like Appendices B and C, is a tool for jurisdictions looking for guidance in establishing access requirements. Some of the other requirements found in this appen- dix address access layouts for multiple -family residen- tial developments and large one- and two-family subdivisions. Also, specific examples for various types of turnarounds for fire department apparatus and park- ing regulation signage are included. SECTION D101 GENERAL D101.1 Scope. Fire apparatus access roads shall be in accor- dance with this appendix and all other applicable require- ments of the International Fire Code. ❖ If this appendix has been adopted by a jurisdiction, this particular section simply states that all fire appa- ratus access roads must meet the requirements of this appendix and other applicable requirements. More specifically, Section 503 would also apply. Be aware that essentially all roads leading to a par- ticular building or facility, whether public or private, are fire apparatus access roads. Generally, the requirements of this appendix and Section 503 would be required only for new buildings and facilities. How- ever, in some cases, improvements to existing roads and access ways may be necessary to meet the needs of the fire department. Note that the appendix applies only if specifically adopted by ordinance by a jurisdiction. See the com- mentary to Sections 102.5 and 507.1 for a discussion of this appendix's application (if adopted) to buildings constructed under the International Residential Code® (IRC®), SECTION D102 REQUIRED ACCESS D102.1 Access and loading. Facilities, buildings or portions of buildings hereafter constructed shall be accessible to fire department apparatus by way of an approved fire apparatus access road with an asphalt, concrete or other approved driv- ing surface capable of supporting the imposed load of fire apparatus weighing at least 75,000 pounds (34 050 kg). ❖ This section contains more detailed specifications for the road surface and applied loads. In Section 503, it simply states that the road must be able to withstand the loads and be of "all-weather driving capability." This section states that the surface be of asphalt, concrete or other approved material and be able to withstand a load of 75,000 pounds (34 050 kg). 2012 INTERNATIONAL FIRE CODE®COMMENTARY APPENDIX D-1 APPENDIX D SECTION D103 MINIMUM SPECIFICATIONS D103.1 Access road width with a hydrant. Where a fire hydrant is located on a fire apparatus access road, the mini- mum road width shall be 26 feet (7925 mm), exclusive of shoulders (see Figure D103.1). ❖ The access road width of 20 feet (6096 mm) stated in Section 503 does not specifically account for the presence of the hydrant. This section specifically requires a minimum width of 26 feet (7925 mm) when a hydrant is located along that access roadway (see Figure D103.1). This provides more room for the fire department vehicle to maneuver and connect to the hydrant. In many cases, a full 26 -foot (7925 mm) width may not be possible for a majority of the access road and a possible solution is to simply widen the access road for a short distance to accommodate hydrant use. Including adjacent road shoulders in the width measurement could yield substandard and inadequate driving surfaces for apparatus. Accord- ingly, this section makes it clear that any road shoul- ders are not to be included in the minimum fire apparatus access road width. Section 503 is generic because available water supplies are not always accessed using hydrants. In some cases, the water comes from a tanker or from an on -site water supply.

Exception: Grades steeper than 10 percent as approved by the fire chief. ❖Section 503 discusses grade in generalities and states that the grade be within the limits established by the fire code official. The criteria are generic because the conditions in different jurisdictions will vary. For example, some fire department apparatus is able to handle steeper grades than others, and the likelihood of inclement weather, such as snow, will affect the ability of the vehicles to handle the terrain. This appendix states a numerical criterion of not more than 10 percent, which is fairly conservative for most situations. This number gives something spe- cific for a jurisdiction to cite without having to deter- mine the actual grade. There is an exception to this section that would allow the fire chief to approve a grade greater than 10 percent. This gives the jurisdic- tion flexibility for specific situations where terrain might call for a steeper grade. D103.3 Turning radius. The minimum turning radius shall be determined by the fire code official. •) The turning radius is left generic within both Section 503 and this section because of the large variation in 28' R TYP. 70' 20' 20' 20' J 26' 20' MINIMUM CLEARANCE AROUND A FIRE HYDRANT 20' ACCEPTABLE ALTERNATIVE TO 120 -FOOT HAMMERHEAD FIGURE D103.1 DEAD-END FIRE APPARATUS ACCESS ROAD TURNAROUND APPENDIX D-2 2012 INTERNATIONAL FIRE CODOCOMMENTARY APPENDIX D the equipment used by fire departments. Each fire department must assess the specific abilities of its vehicles to set a minimum turning radius. The dia- grams in Figure 0103.1 set the turning radius at 28 feet (8534 mm), which may not be satisfactory for all jurisdictions. D103.4 Dead ends. Dead-end fire apparatus access roads in excess of 150 feet (45 720 mm) shall be provided with width and turnaround provisions in accordance with Table D103.4. TABLE D103.4 REQUIREMENTS FOR DEAD-END FIRE APPARATUS ACCESS ROADS LENGTH (feet) 0-150 20 None required 120 -foot Hammerhead, 60 -foot "Y" 151-500 20 or 96 -foot diameter cul-de-sac in accordance with Figure D 103.1 120 -foot Hammerhead, 60 -foot "Y" 501-750 26 or 96 -foot diameter cul-de-sac in accordance with Figure D103.1 Over 750 Special approval required WIDTH (feet) TURNAROUNDS REQUIRED or SI: 1 foot 304.8 mm. ❖Though the widths of the access roadways may be sufficient to move and operate the necessary equip- ment at a fire scene, they may not be wide enough for the vehicles to turn around. On through streets this is not an issue, but when the road is a dead end and is sufficiently long, some means are necessary to enable fire department vehicles to turn around rather than having to back up over excessive distances. The three major methods used to provide a turn -around area are a cul-de-sac, hammerhead and "Y." Figure D103.1 shows examples of all three types. Section 503 does not give any specific guidance. Each juris- diction can choose from a variety of ways to accom- plish this. Dead ends require a fire vehicle turnaround when they exceed 150 feet (45 720 mm). The turnaround is to be located at the end of the roadway or within 150 feet (45 720 mm) of the end of the roadway to limit the backing distance to a maximum of 150 feet (45 720 mm). Backing a large vehicle, such as a tower ladder, over 150 feet (45 720 mm) can be especially challenging, especially in cases where the engineer may have to use a video camera -equipped back-up system due to the vehicle's length. Refer to the table for more guidance in determining the kind of turning radius required. In any event, the configuration of the roadway and turnaround must be approved by the fire code official. This table, which is based on the length of a dead end, sets minimum widths and recommends which types of turnarounds should be used. The diagrams in Figure D103.1 show the configurations of these turnarounds. D103.5 Fire apparatus access road gates. Gates securing the fire apparatus access roads shall comply with all of the following criteria: I. The minimum gate width shall be 20 feet (6096 mm). 2. Gates shall be of the swinging or sliding type. 3. Construction of gates shall be of materials that allow manual operation by one person. 4. Gate components shall be maintained in an operative condition at all times and replaced or repaired when defective. 5. Electric gates shall be equipped with a means of open- ing the gate by fire department personnel for emer- gency access. Emergency opening devices shall be approved by thefire code official. 6. Manual opening gates shall not be locked with a pad- lock or chain and padlock unless they are capable of being opened by means of forcible entry tools or when a key box containing the key(s) to the lock is installed at the gate location. 7. Locking device specifications shall be submitted for approval by thefire code official. 8. Electric gate operators, where provided, shall be listed in accordance with UL 325. 9. Gates intended for automatic operation shall be designed, constructed and installed to comply with the requirements of ASTM F 2200. • Gates are sometimes required by the fire code official to limit access to certain hazardous fire areas. They are also often used as a security mechanism for gated communities and complexes. Section 503 dis- cusses the use of gates in more general terms whereas this section provides more specific guide- lines. The nine requirements stated here all must be complied with where applicable. They focus on main- taining the required width, ease of use and ability to open in an emergency. The construction and installa- tion of gates and methods for opening the gates, whether by manual means or by a listed electrical mechanism, must comply with the referenced stan- dards and be approved by the fire code official. This ensures that the operating procedures of the fire department are taken into account. See the commen- tary to Sections 503.5 and 503.6 for further informa- tion on gates. D103.6 Signs. Where required by the fire code official, fire apparatus access roads shall be marked with permanent NO PARKING —FIRE LANE signs complying with Figure D103.6. Signs shall have a minimum dimension of 12 inches (305 mm) wide by 18 inches (457 mm) high and have red let- NTARY 2012 INTERNATIONAL FIRE CODE° COMMENTARY APPENDIX O-3 APPENDIX D ters on a white reflective background. Signs shall be posted on one or both sides of the fire apparatus road as required by Section D103.6.1 or D 103.6.2. ❖One of the more challenging aspects of access roads is maintaining the necessary width. Parked cars can reduce this width if parking is not prohibited and the prohibition is posted. Section 503.3 addresses this need by giving the fire code official the authority to require marking of fire access roads. This section and Figure D103.6 add wording and dimension specifica- tions for the signs needed to mark areas where park- ing is prohibited. SIGN TYPE "A" NO PARKING FIRE LANE Imo---- 12" -a-. SIGN TYPE "C" NO PARKING FIRE LANE -411 12" FIGURE D103.6 FIRE LANE SIGNS SIGN TYPE "D" NO PARKING FIRE LANE 12„ D103.6.1 Roads 20 to 26 feet in width. Fire lane signs as specified in Section D103.6 shall be posted on both sides of fire apparatus access roads that are 20 to 26 feet wide (6096 to 7925 mm), + This section requires that parking be prohibited on both sides of narrower fire apparatus access roads. Twenty feet. (6096 mm) is the appropriate width needed for two average -size fire trucks to pass one another. If that width is reduced by parking even on one side, it will be potentially difficult for a fire depart- ment to undertake emergency operations in that area. D103.6.2 Roads more than 26 feet in width. Fire lane signs as specified in Section D103.6 shall be posted on one side of fire apparatus access roads more than 26 feet wide (7925 mm) and less than 32 feet wide (9754 mm). •:• Because this width is more than sufficient for maneu- vering at least two fire department vehicles by one another, parking would be allowed on one side. SECTION D104 COMMERCIAL AND INDUSTRIAL DEVELOPMENTS D104.1 Buildings exceeding three stories or 30 feet in height. Buildings or facilities exceeding 30 feet (9144 mm) or three stories in height shall have at least two means of fire apparatus access for each structure. ❖ This section addresses commercial and industrial buildings that, because of their height, have the potential of creating a large challenge to a fire depart- ment. This section, along with Sections D105, D106 and D107, contains requirements for fire apparatus access roads for specific kinds of buildings or devel- opments. Section 503 gives the fire code official the authority to require more access roads but does not specify when the additional roads are required. The need for additional access roads will depend on so many factors that each situation must be judged indi- vidually. Because of the height of these buildings, various types of vehicles may be needed, and having two or more means of approaching the site may be neces- sary to manage and manipulate the vehicles. D104.2 Buildings exceeding 62,000 square feet in area. Buildings or facilities having a gross building area of more than 62,000 square feet (5760 m2) shall be provided with two separate and approved fire apparatus access roads. Exception: Projects having a gross building area of up to I24,000 square feet (11 520 m2) that have a single 18" approved fire apparatus access road when all buildings are equipped throughout with approved automatic sprinkler systems. •:• Where buildings are very large in area, two separate fire apparatus access roads are required because a large building may be difficult to access rapidly and, if one of the access roads is blocked, there is a poten- tial for a large fire loss. The exception acknowledges the ability of automatic sprinklers to prevent most fires from growing out of control quickly even when the building area is doubled and there is only a single, approved fire apparatus access road. D104.3 Remoteness. Where two fire apparatus access roads are required, they shall be placed a distance apart equal to not less than one half of the length of the maximum overall diag- onal dimension of the lot or area to be served, measured in a straight line between accesses. + This concept is similar to the one dealing with the remoteness of exits in Section 1015.2. One of the pri- mary reasons for multiple access roads is to ensure that if one access road is blocked or otherwise unavailable, another will allow access to the fire department. Therefore, when more than one access road is required, they need to be separated by enough distance to avoid a situation where both would be blocked or unavailable simply because they are too close to one another. SECTION D105 AERIAL FIRE APPARATUS ACCESS ROADS DI05.1 Where required, Where the vertical distance between the grade plane and the highest roof surface exceeds 30 feet (9144 mm), approved aerial fire apparatus access roads shall be provided. For purposes of this section, the highest roof surface shall be determined by measurement to the cave of a pitched roof, the intersection of the roof to the exterior wall, or the top of parapet walls, whichever is greater. •: Where building height exceeds 30 feet (9144 mm) above grade plane, the use of aerial fire apparatus APPENDIX D-4 2012 INTERNATIONAL FIRE CODE® COMMENTARY APPENDIX D becomes more necessary. This section states, in general terms, that the fire access roads must be capable of handling the larger aerial equipment and provides the lower and upper reference points for measuring the vertical distance that determines the requirement. See also the commentary to the defini- tion of "Grade plane" in Chapter 2. D105.2 Width. Aerial fire apparatus access roads shall have a minimum unobstructed width of 26 feet (7925 mm), exclu- sive of shoulders, in the immediate vicinity of the building or portion thereof. + This section specifies the minimum road width needed for aerial apparatus. This width allows the aerial apparatus outriggers to be set solidly on the road surface for safe operation of the aerial equip- ment. Including adjacent road shoulders in the width measurement could yield substandard and inade- quate driving or set-up surfaces for aerial apparatus. Accordingly, this section makes it clear that any road shoulders are not to be included in the minimum fire apparatus access road width. D105.3 Proximity to building. At least one of the required access routes meeting this condition shall be located within a minimum of 15 feet (4572 mm) and a maximum of 30 feet (9144 mm) from the building, and shall be positioned parallel to one entire side of the building. The side of the building on which the aerial fire apparatus access road is positioned shall be approved by the fire code official. This section requires that the access road be specifi- cally located where aerial equipment will have maxi- mum access to the building. The fire code official, in consultation with the fire chief, must approve the final location of the aerial fire apparatus access road required by this section. Although not stated in this section, fireground operation protocols often place an aerial apparatus/truck company on the front side of the building so that the entire front, which could include emergency escape and rescue openings, can be reached by the ladder or the tower basket. The road that will meet the requirements of this section will often be the public street upon which the building fronts. The distance from the building to the road must be reviewed and approved to match the capabil- ities of the fire department aerial equipment versus the building's height. D105.4 Obstructions. Overhead utility and power lines shall not be located over the aerial fire apparatus access road or between the aerial fire apparatus road and the building. Other obstructions shall be permitted to be placed with the approval of the fire code official. •:• This section establishes requirements for controlling overhead obstructions to aerial fire apparatus posi- tioned on aerial fire apparatus access roads to avoid the possibility of personnel injury and equipment damage, especially from electrical shock. The requirements prohibit overhead obstructions between the aerial fire apparatus access road and the building, but permit the fire code official to allow limited obstructions that do not affect the placement or use of aerial fire apparatus, such as site vegetation or a porte' cochere at the entrance to a building. SECTION D106 MULTIPLE -FAMILY RESIDENTIAL DEVELOPMENTS D106.1 Projects having more than 100 dwelling units. Multiple -family residential projects having more than 100 dwelling units shall be equipped throughout with two sepa- rate and approved fire apparatus access roads. Exception: Projects having up to 200 dwelling units may have a single approved fire apparatus access road when all buildings, including nonresidential occupancies, are equipped throughout with approved automatic sprinkler systems installed in accordance with Section 903.3.1.1 or 903.3.1.2. ❖This section is intended to provide some specific guidance to jurisdictions for dealing with larger apart- ment complexes. Again, Section 503 suggests that more than one access road is needed when there is a potential for an access road to be unavailable. In a large complex there is a large potential for loss. Lack of access should not become a factor in such a loss. This section requires at least two separate access roads any time the number of dwelling units exceeds 100. The term "approved" is used because the layout of the complex may require some specific consider- ations when providing the access roads. For exam- ple, having two access roads leading onto a facility that come together before reaching the actual build- ings may not satisfy the criterion of remoteness to be effective in an emergency. The exception would allow a single access road for up to 200 dwelling units if all buildings on the site are fully sprinklered to meet code requirements. This exception acknowledges the effectiveness of sprin- klers in slowing the growth of fires; therefore, the risk of having the access road blocked or unusable is more acceptable. D106.2 Projects having more than 200 dwelling units. Multiple -family residential projects having more than 200 dwelling units shall be provided with two separate and approved fire apparatus access roads regardless of whether they are equipped with an approved automatic sprinkler sys- tem. + Because of the large size of such complexes and the potential for large losses, even where sprinklers are installed as required by Section 903.2.8, two approved access roads must be provided. This sec- tion emphasizes that the exception in Section D106.1 is for up to 200 units only. 2012 INTERNATIONAL FIRE CODE° COMMENTARY APPENDIX O-5 APPENDIX D SECTION D107 ONE- OR TWO-FAMILY RESIDENTIAL DEVELOPMENTS D107.1 One- or two-family dwelling residential develop- ments. Developments of one- or two-family dwellings where the number of dwelling units exceeds 30 shall be provided with two separate and approved fire apparatus access roads, and shall meet the requirements of Section D104.3. Exceptions: 1. Where there are more than 30 dwelling units on a single public or private fire apparatus access road and all dwelling units are equipped throughout with an approved automatic sprinkler system in accor- dance with Section 903.3.1.1, 903.3.1.2 or 903.3.1.3 of the International Fire Code, access from two directions shall not be required. 2. The number of dwelling units on a single fire appa- ratus access road shall not be increased unless fire apparatus access roads will connect with future development, as determined by the fire code official. ❖ This section requires that one- and two-family dwell- ing subdivisions with more than 30 dwellings have more than one fire apparatus access road into the development. The second access road is needed in case one access road for any reason becomes unus- able. The two access roads must also be remote from one another as required by Section D104.3 to reduce the likelihood that both access roads would be com- promised by a single fire or other emergency event. Exception 1 states that when there are more than 30 dwelling units equipped throughout with an approved sprinkler system in accordance with NFPA 13, 13R or 13D, as applicable or approved, a second access road is not required. This recognizes the effectiveness and reliability of properly designed and installed automatic sprinkler systems in mitigating the need to have two access points. Exception 2 requires approval by the fire code offi- cial any time a new house is constructed on an exist- ing access road. Once the maximum number of dwelling units allowed by this section has been reached, no further development may occur unless the fire code official determines that there will be a future road connection that will prevent creation of an excessive dead-end situation with no means for apparatus turn -around. Such determination by the fire code official should consider the phased -develop- ment of an individual project or adjacent projects. Requiring evidence of legal agreements for specific future development would be prudent, especially in times of economic uncertainty. This gives the fire code official an opportunity to assess whether addi- tional access is required in the interim.

Will you please replace the letter I sent to you yesterday with the letter below? I apologize for the confusion, and please let me know if you have any questions or concerns. The formal comments I would like to submit are as follows: "Thank you for the opportunity to review and comment on the above referenced application. A portion of the Property is located in Brighton's Urban Growth Boundary. The City of Brighton has several concerns with the proposed use and appreciates the opportunity to provide formal comments that will help to mitigate those concerns. Generally, the City is not in favor of the application. In accordance with "Urban Development," Section 22-2- 30, of the County's Comprehensive Plan, the City of Brighton believes the application is incompatible with the County's policy to segregate heavy industrial uses on the perimeters and away from developing urban communities. This section of the code encourages urban development to locate along major roadways with available services and infrastructure. The property in question is located along WCR 27, which has adequate services and infrastructure in place to support urban development. WCR 27 is a rapidly urbanizing corridor where Weld County, the State of Colorado, the City of Fort Lupton, and the City of Brighton have worked together to encourage and incentivize a "New Energy Corridor," to synthesize the locating of jobs and businesses related to the energy industry, especially the alternative energy industry, along the WCR 27 corridor. In particular, the City is not in favor of the proposal for recycling of asphalt and concrete and the 20 year timeframe for mineral extraction. The City is concerned with the traffic impacts on Brighton's transportation system and on traffic for the region, the aesthetic impact on Brighton's northern gateway, noise and air pollution, and the adverse impacts on the future expansion plans of the Vestas campus located directly south of this Property. As the property in question is zoned as I-3 (the heaviest industrial zoning designation in Weld County), the City understands that the proposed uses are allowed by the County's zoning regulations as a Use By Special Review. However, should the County decide in favor of the application, the City of Brighton appreciates the County's efforts to "minimize the incompatibilities that occur between industrial uses and surrounding properties" in accordance with Goal #6 of Section 22-2-80 of the County's Comprehensive Plan. 1 According to EP Goal #2 of Section 22-4-130 of the County's Comprehensive Plan, "Mineral resource facilities should be planned, located, designed and operated to encourage compatibility with surrounding land uses in terms of use, scale, height, traffic, dust, noise, and visual pollution." In accordance with this goal, the City of Brighton is requesting that, should the County approve the application, the following items be addressed: 1. Please prohibit the use of crushing or blasting operations on this Property. Per Goal #6 of Section 22-2- 80 of the County's Comprehensive Plan, the City believes the noise and air pollution created by such operations are incompatible with the urbanizing corridor as well as the existing agricultural and residential land uses in the vicinity of the Property and, thus, should be prohibited. 2. Please prohibit or severely limit the proposed asphalt or concrete recycling operations on this Property. Per Goal #6 of Section 22-2-80 of the County's Comprehensive Plan, the City believes the noise and air pollution created by such operations are incompatible with the urbanizing corridor as well as the agricultural and residential land uses in the vicinity of the Property and, thus, should be prohibited or limited to the northern portion of the site. 3. Should the County approve the application, the City of Brighton requests that the property be landscaped and screened from view, in accordance with the zoning code requirements to screen outdoor storage and Goal 6.2 of Section 22-2-80 of the Comprehensive Plan. 4. Please require the site to be reclaimed in order to provide for redevelopment opportunities after the mineral extraction operations are completed. As previously noted, a portion of this Property is located within Brighton's Urban Growth Boundary area. Per UD Goal #1 of Section 22-2-40 of the County's Comprehensive Plan, urban development should be concentrated in approved Intergovernmental Agreement urban growth areas, such as the WCR 27 corridor. 5. Please require conveyor equipment to be utilized for the loading of vehicles in order to diminish noise and air pollution. 6. Please require dust suppression best practices to be utilized to reduce air pollution and topsoil erosion. 7. Please prohibit any traffic associated with the operations from utilizing those portions of WCR 6 or WCR 27 that are annexed to the City of Brighton. Due to traffic conflicts with oversized Vestas vehicles and the impact on the City's roadway infrastructure, the City opposes any traffic related to the application from utilizing the City's roadway infrastructure without a maintenance agreement with the City of Brighton. Per Policy 3.2 of Section 22-2-80 of the County's Comprehensive Plan, the applicant must demonstrate the roadways that serve the Property are adequate to accommodate the traffic generated by the use. Also, per Goal #4, which requires new industrial development to pay its own way, the roadway network must be improved and maintained by the developer in order to pay for those costs associated with the impacts of that development. 8. The timeframe for mineral extraction should be limited to 10 years in order to ensure expedited removal of mineral resources and reclamation of the Property for redevelopment. 9. Information regarding public hearings associated with the Property and proposed operations be sent to Mary Falconburg - mfa1conburnii brightonco.uov, Assistant City Manager of Development; Holly Prather - hprathcr(cr;_bru htonco.gov, Community Development Director; Kimberly Dall - kda11(cr;_hrightonco.gov, Streets and Fleet Director; and Jason Bradford - jhradford(tr;_bridhtonco.gov, Planning Division Manager. Thank you, again, for the opportunity to review and comment on this proposed land use. The City of Brighton appreciates the cooperative relationship we have with Weld County and requests that the above comments be addressed to ensure the right to mineral extraction for the Property are provided for while also respecting the City of Brighton's right to plan for those properties located within Brighton's boundary and the future of those lands located within our Urban Growth Boundary." Please let me know if you have any comments or questions. 2 Cordially, Jason Bradford, AICP Planning Manager Community Development City of Brighton 500 South 4th Avenue Brighton, CO 80601 303-655-2024 Brighton Integrity + Vision + Stewardship = A Progressive Community Think green ...reduce, reuse, recycle. 3 Diana Aungst Subject: Attachments: FW: Inert Fill as a Reclamation Plan for a Sand & Gravel Mine in Weld County HM_sw-beneficial-use-of-asphalt-brick-concrete.pdf; HM_sw-reps-butable3.pdf From: Bankoff - CDPHE, Michael [mailto:michael.bankoff@state.co.us] Sent: Wednesday, November 30, 2016 10:27 AM To: Diana Aungst <daungst@co.weld.co.us> Cc: Ben Frissell <bfrissell-durley@co.weld.co.us>; Kim Ogle <kogle@co.weld.co.us>; Troy Swain <tswain@co.weld.co.us>; David Snapp - CDPHE <david.snapp@state.co.us>; Peter Hays - DNR <peter.hays@state.co.us> Subject: Re: Inert Fill as a Reclamation Plan for a Sand & Gravel Mine in Weld County Good morning Diana, Below are a few comments we have regarding mine reclamations that incorporate imported recyclable inert materials. 1. CDPHE would not require a certificate of designation if the reclamation (backfilling using soil, concrete and asphalt) is being done under a DRMS reclamation permit. It sounds like this is what Valley's Edge Resource will have (unless I'm mistaken). 2. "Inert material" means non-watersoluble and non-putrescible solids together with such minor amounts and types of other materials as will not significantly affect the inert nature of such solids. The term includes, but is not limited to, earth, sand, gravel, rock, concrete which has been in a hardened state for at least sixty days,masonry, asphalt paving fragments, and other inert solids. Solid Waste Regulations, 6 CCR 1007-2, Part 1, § 1.2 Inert materials maybe solid wastes unless they are handled in a way allowing for an exemption from the solid waste regulations outlined below. 3. If the reclamation does not take place under a DRMS reclamation permit, the final disposition of the waste in a mine would need a Certificate of Designation from the county or a Beneficial Use Determination from CDPHE. However, the recycling of the concrete and asphalt may not be subject to the solid waste regulations if the imported material is being processed for recycling purposes and sent offsite in accordance with the exemptions in Section 8.5.3 of the Regulations Pertaining to Solid Waste Sites and Facilities, 6 CCR 1007-2, Part 1 ("the Solid Waste Regulations"). Section 8.5.3 states: The following operations are exempt from Section 8.5: (A) On -site recycling operations where the processing of recyclable materials occurs on the same site from where the recyclable materials are generated and that recycle and store only materials generated on -site and meet the performance criteria of 8.5.2. Creation of ground water contamination, off -site odors, and speculative accumulation of waste materials voids this exemption. (B) Concrete and asphalt operations when the material is managed like a commodity' by meeting the following conditions: (1) material is managed and separated into commodity specific piles processed for reuse; (2) material is managed in active piles separated by material type or use within the past year; and (3) Incoming loads shall have all non -concrete, non -asphalt and nonrebar material removed from concrete and asphalt materials within thirty (30) calendar days and non -concrete, non -asphalt and nonrebar material shall not exceed 10% of the total material onsite by weight or volume. (C) Environmental media storage and reuse. 4. All imported waste material would need to be able to qualify as an inert material. C+D waste must be asbestos -free. Soil must be known to be free of chemical contamination by sampling and testing and/or generator knowledge that the soil originating site is free from known environmental impacts. Attached is a guidance document regarding the reuse and recycling of asphalt, brick, and concrete which maybe useful. Additionally, I have attached Table 3 from the beneficial use regulations which identifies materials that are pre -approved for reuse so long as they are reused in one of the specified beneficial uses for the material. You may notice that in the asphalt category on this table we do not have a pre -approved use as an aggregate substitute. In the near future, we will likely be adding that in there when used in mine reclamation activities overseen by 1 DRMS. For the time being, as long as this operation has a DRMS reclamation permit, reuse of asphalt as an aggregate substitute for backfill should be fine. I hope this helps and feel free to contact me should you have any additional questions or concerns. Thank you, - Mike Michael Bankoff Environmental Protection Specialist Materials Management Unit P 303.692.3438 I F 303.759.5355 43O0 Cherry Creek Drive South, Denver, CO 80246 rrtichacl.ban koff<a slalc.co.us I blips::: vyk. u.colorado.gov.pdcificicdphc 2 Compliance Bulletin COLORADO Department of Public Health & Environment Asphalt, Brick and Concrete Recycling & Beneficial Use February 2016 Asphalt, brick and concrete material accounts for millions of tons of construction and demolition debris every year in the U.S. Recycling this material can create jobs, save valuable landfill space, and reduce the environmental impacts from mining new materials. Since asphalt, brick and concrete can often be recycled on the job site at reduced expense when compared to disposal alternatives, it can also provide significant savings during construction by avoiding new material purchase and waste disposal costs. Applicability This guidance is for material that contains only fully cured asphalt pavement, clay bricks and attached mortar, or fully cured concrete (with or without rebar). Asphalt, brick, and concrete containing paint, adhesives, mastics, sealants, or other coatings must be tested to ensure the coatings do not contain asbestos or lead paint before this guidance may be applied. Industrial Recycling Operations Exemption Section 8.5 of the Regulations Pertaining to Solid Waste Sites and Facilities (6 CCR 1007-2, Part 1) specifies the requirements for industrial recycling operations, including for the recycling of asphalt, brick, and concrete. Facilities that recycle these materials are subj ect to all of the requirements found in Section 8.5 unless the facility meets one or more of the exemptions in Section 8.5.3. The first exemption includes on -site recycling operations that 1) process recyclable materials on the same site where the recyclable materials were generated and 2) recycle and store only materials generated on -site. These operations must meet certain performance criteria, including meeting established engineering, product, end user, customer, or other appropriate specifications; demonstrating a benefit associated with use of the material; and showing the material is used as a substitute for, or in conjunction with, a commercial product or raw material. Creation of ground water contamination, off -site odors, and/ or speculative accumulation of waste materials voids this exemption. The second exemption applies to concrete and asphalt operations where the material is managed like a commodity by meeting the following conditions: 1) the material is managed and separated into commodity -specific piles processed for reuse, 2) the material is managed in active piles separated by material type within one year of receipt, and 3) incoming loads have all non -concrete, non -asphalt and non-rebar material removed from the concrete and asphalt materials within thirty (30) calendar days. In addition, any material that is not asphalt, brick, concrete, or rebar cannot exceed 10% of the total material onsite by weight or volume. If a recycling operation meets either or both of the first two exemptions, it is exempt from the requirements of Section 8.5, including facility registration, general site requirements and closure requirements. However, any use of the recycled material must meet the recyclable material performance criteria of Section 8.5.2. Pre -Approved Beneficial Uses The Colorado Department of Public Health and Environment (the Department) has approved beneficial uses for several types of uncontaminated materials in the Pre -Approved Beneficial Use Table 3, available on our website at www.colorado.gov/ cdphe/ swregs. Clean, uncontaminated asphalt, brick and concrete material may be recycled and used in a variety of ways that do not require consultation and specific approval from the department. Determining what qualifies as "clean and uncontaminated" requires not only a thorough inspection of the material to look for obvious signs of contamination such as odor, staining, discoloration or the presence of adhered materials, but also a thorough understanding of the site history and possibly sampling and laboratory analysis if there is any reason to suspect contamination. Ideally, any contamination issues would have been found during a Phase I and/ or Phase II Environmental Site Assessment or asbestos building inspection. If no such investigation has been performed, then it is very important to perform a thorough inspection prior to beginning the recycling process. Future liability issues may be avoided by taking steps to properly characterize the material as uncontaminated. The table below, taken from the Pre -Approved Beneficial Use Table 3, shows the approved uses for uncontaminated asphalt, brick and concrete. Reclaimed Asphalt Road Base Component of hot or cold mix asphalt Re -compacted asphalt Roadside dressing Chip seal material Culvert cover Base stabilization Reclaimed Concrete, Brick and Stone Road base (non -asbestos bearing materials) Concrete aggregate Component of engineered structural fill Aggregate substitute Engineered rip rap Roadside dressing While these uses are pre -approved by the Department, a number of other conditions do apply. Key conditions on the pre -approved beneficial use of asphalt, brick, and concrete material include: 1) when using crushed material as a component of structural fill, crush the material to six inches or less, or size according to an engineer's backfill specification, and 2) ensure a minimum of three feet of separation between the placement of the material and the seasonally high ground water level. All of the required conditions can be found in Section 8.6.2 of Part 1 of the solid waste regulations, available on our website at www.colorado.gov/ cdphe/ swreqs. If uncontaminated asphalt, brick or concrete will not be directly reused, there are many facilities that will accept these materials for recycling. Other Beneficial Uses If the intended recycling and reuse of the asphalt, brick and concrete material is not found on the pre -approved list above, it may still qualify for beneficial use with our approval. In order for the Department to approve your beneficial use project, you must submit an "Application for a Solid Waste Beneficial Use Determination." The application form includes a list of performance criteria that must be met and a checklist of attachments that must be included in order for the Department to evaluate the project. The application form may be found on our website at www.colorado.gov/ cdphe/ swforms. Recycling and Beneficial Use Best Management Practices The ability to recycle asphalt, brick and concrete material safely and in a manner protective of public health and the environment requires not only meeting the requirements of the solid waste and asbestos regulations, but also following established best management practices. • Ensure that only uncontaminated material is crushed and processed. o Know the results of the Phase I or II Environmental Site assessment (ESA). o If no environmental site assessment was performed: 2 ▪ Perform a thorough visual inspection of the materials. ▪ Learn the site history and whether prior contamination may have occurred. ▪ Perform sampling and laboratory testing if there are any doubts whether the material may be contaminated. • If the material came from a structure, ensure that a state demolition permit was issued and that all suspect asbestos -containing materials (including all nonfriable materials) were tested and do not contain asbestos. • Do not crush material that has paint, finishes, adhesives, mastics, sealants, coatings or any other potential contaminants until the material is tested for lead and asbestos. • Properly size and engineer the material for the intended use in accordance with the recommendations of a professional engineer. • Manage and separate the material into commodity -specific piles for processing and reuse. • Remove and recycle any rebar from the concrete. • Notify the relevant local authorities of the intended activity to gain any necessary permits and approvals before crushing or material processing begins. • Do not allow any unpermitted discharges to air, water, or other environmental resources. • Avoid creating nuisance conditions such as fugitive dust, excessive noise, or allowing exhaust or fumes to drift off -site. Waste Disposal If there is obvious staining and discoloration, or if the site was previously home to a type of facility frequently found to be contaminated such as a dry cleaner, a gas station, or an industrial facility, then sampling and analysis should be performed on the material. Also, be aware that certain types of brick (e.g., refractory brick) and concrete may be associated with asbestos and should be tested even if there may be no obvious evidence such as remnants of floor tile or mastic. If the condition of the material is not suitable for reuse or recycling, then it will have to be disposed of as solid or hazardous waste. Knowledge of the site history along with analytical results will help determine what type of disposal is required. Contact the Department if additional information regarding sampling and analysis requirements or assistance with determining the type of disposal is needed. Other Applicable Regulations Crushing of asphalt, brick or concrete materials at a facility or on the work site may be subject to air permitting requirements. For more information, please contact the Air Pollution Control Division at 303-692-3100 or cdphe. commentsapcdAstate.co.us. Stormwater permitting may be required for facilities or work sites that are recycling asphalt, brick or concrete materials.

USR16-0034 Portions of the N'h of the SW 1/4, 5'/2 of the NW /, the SW / of the NE /, and the NW / of the SE 1/4, all in Sec. 20, TIN, R66W, 6th P.M. Water Division 1, Water District 2 Dear Ms. Aungst, This referral does not appear to qualify as a "subdivision" as defined in Section 30-28-101(10)(a), C.R.S. Therefore, pursuant to the State Engineer's March 4, 2005 and March 11, 2011 memorandums to county planning directors, this office will only perform a cursory review of the referral information and provide informal comments. The comments do not address the adequacy of the water supply plan for this project or the ability of the water supply plan to satisfy any County regulations or requirements. In addition, the comments provided herein cannot be used to guarantee a viable water supply plan or infrastructure, the issuance of a well permit, or physical availability of water. The applicant is requesting a Special Use Permit to allow for a gravel mining operation (M-2016- 030) on a 190 acre site that includes properties with Parcel IDs 147120000033, 147120000023, and 147120300008. The applicant anticipates that the mining operation will consist of mining four cells in four stages, with each cell being approximately 27 acres. The operation is anticipated to last 10-20 years; the site will be backfilled and reclaimed to allow for the subsequent development of an industrial complex. The site will have approximately 10 on -site employees. The operator will initially mine in a cell to test a temporary floor above groundwater, sufficient to avoid exposure, depletions, or other conditions requiring augmentation or a substitute water plan. Once a floor has been established and any required State Engineer or Water Court approval is obtained, a wet mining state may proceed concurrently or subsequently to dry mining. The proposed water supply for the project is the Fulton Ditch or adjudicated water from a well (gravel well or existing Central Colorado Water Conservancy District Well) for limited 1313 Sherman Street, Room 821, Denver, CO 80203 P 303.866.3581 F 303.866.3589 www.water.state.co.us Regional Transportation District Use by Special Review Permit November 1, 2016 Page 2 of 2 augmentation water needs. Fully consumable water will be imported to the site or obtained through permitted wells. Bottled water and portable lavatories will be provided for employees. The applicant is proposing to "divert on -site storm water into perimeter trenches." According to the drainage narrative, runoff to the site is currently intercepted by the Fulton Ditch and carried toward existing infiltration ponds. The applicant indicates that this practice will continue to do this for their planned storm water management plan. The Fulton Ditch is not a drainage ditch but an active structure designed for diverting water rights to place to subsequent use. The disposal of storm water into this structure could impact the administration of the structure, its ability to divert its water rights, and/or its physical integrity. At no point should the storm water management plan be designed to discharge water into an active water diversion structure without prior approval of the owner of the structure and the Division One Engineer. The applicant also indicated that storm water within the active mining and reclamation areas will be directed to the pit floor, where it will infiltrate. The applicant should be aware that, unless the pit structure can meet the requirements of a "storm water detention and infiltration facility" as defined in section 37-92-602(8), Colorado Revised Statutes, the structure may be subject to administration by this office. The applicant should review DWR's Administrative Statement Regarding the Management of Storm Water Detention Facilities and Post-Wildland Fire Facilities in Colorado, attached, to ensure that the notification, construction and operation of the proposed structure meets statutory and administrative requirements. The applicant is encouraged to use Colorado Stormwater Detention and Infiltration Facility Notification Portal, located at https://maperture.digitaldataservices.com/gvh/?viewer=cswdif, to meet the notification requirements. It appears there are several existing wells located on the gravel pit site. The applicant has not provided details regarding the proposed water supply for dust suppression or other operational water needs; therefore this office cannot comment on the proposed water supply. However, any use of the on -site wells should comply with the existing well permits. Any use of Fulton Ditch water must fit within the decreed uses of said water rights. Similarly, any use of water trucked in from another source must be legally available for the on -site uses. No groundwater should be exposed on -site until a Substitute Water Supply Plan has been approved by this office or a plan for augmentation that has been decreed by the Water Court, and a valid gravel pit well permit, is in place. If you, or the applicant, have any questions please contact Karlyn Armstrong of this office. 4)4,/ Williams, P.E. Resource Engineer 1313 Sherman Street, Room 821, Denver, CO 80203 P 303.866.3581 F 303.866.3589 www.water.state.co.us COLORADO Division of Water Resources Dena -triter of Natural Resou.rces 1313 Sherman Street, Room 821 Denver, CO 80203 Administrative Statement Regarding the Management of Storm Water Detention Facilities and Post-Wildland Fire Facilities in Colorado February 11, 2016 The Division of Water Resources (DWR) has previously administered storm water detention facilities based on DWR's "Administrative Approach for Storm Water Management" dated May 21, 2011. Since the passage of Colorado Senate Bill 15-212, that administrative approach has been superseded. This document describes SB 15-212, codified in section 37-92-602(8), Colorado Revised Statutes (C.R.S.), and how the law directs administrative requirements for storm water management. The document is for informational purposes only; please refer to section 37-92- 602(8) for comprehensive language of the law. Pursuant to section 37-92-602(8), storm water detention facilities and post-wildland fire facilities shall be exempt from administration under Colorado's water rights system only if they meet specific criteria. The provisions of SB15-212 apply to surface water throughout the state. SB15-212 only clarifies when facilities may be subject to administration by the State Engineer; all facilities may be subject to the jurisdiction of other government agencies and must continue to obtain any permits required by those agencies. Storm Water Detention Facilities Pursuant to section 37-92-602(8), a storm water detention and infiltration facility ("Detention Facility") is a facility that: • Is owned or operated by a government entity or is subject to oversight by a government entity, including those facilities that are privately owned but are required by a government entity for flood control or pollution reduction. • Operates passively and does not subject storm water to any active treatment process. • Has the ability to continuously release or infiltrate at least 97 percent of all of the water from a rainfall event that is equal to or less than a five-year storm within 72 hours of the end the rainfall event. • Has the ability to continuously release or infiltrate at least 99 percent of all of the water from a rainfall event that is greater than a five-year storm within 120 hours of the end the rainfall event. • Is operated solely for storm water management. 1313 Sherman Street, Room 821, Denver, CO 80203 P 3O3.866.3581 F 3O3.866.3589 www.water.state.co.us Administrative Statement: Storm Water and Post-Wildland Fire Facilities, DWR February 11, 2016 Page 2 of 5 In addition, to qualify for the allowances provided in SB-212, the facility: • Must not be located in the Fountain Creek watershed, unless the facility is required by or operated pursuant to a Colorado Discharge Permit System Municipal Separate Storm Sewer System Permit issued by the Department of Public Health and Environment pursuant to Article 8 of Title 25, C.R.S. • Must not use water detained in the facility for any other purpose nor release it for subsequent diversion by the person who owns, operates, or has oversight over the facility. The facility cannot be operated as the basis for a water right, credit, or other water use right. • Must not expose ground water. • May include a structure or series of structures of any size. If the Detention Facility was constructed on or before August 5, 2015 and meets all the requirements listed above, it does not cause material injury to vested water rights and will not be subject to administration by the State Engineer. If the Detention Facility is constructed after August 5, 2015, meets the requirements listed above, and the operation of the detention facility does not cause a reduction to the natural hydrograph as it existed prior to the upstream development, it has a rebuttable presumption of non -injury pursuant to paragraph 37-92-602(8)(c)(II). A holder of a vested water right may bring an action in a court of competent jurisdiction to determine whether the operation of the detention facility is in accordance with paragraph 37-92-602(8)(c)(II)(A) and (B) has caused material injury. If the court determines that the vested water rights holder has been injured, the detention facility will be subject to administration. In addition, for Detention Facilities constructed after August 5, 2015, the entity that owns, operates, or has oversight for the Detention Facility must, prior to the operation of the facility, provide notice of the proposed facility to the Substitute Water Supply Plan (SWSP) Notification List for the water division in which the facility is located. Notice must include: the location of proposed facility, the approximate surface area at design volume of the facility, and data that demonstrates that the facility has been designed to comply with section 37-92-602(8)(b) paragraphs (B) and (C). The State Engineer has not been given the statutory responsibility to review notices, however, DWR staff may choose to review notices in the course of their normal water administration duties. Not reviewing notices does not preclude the Division Engineer from 1313 Sherman Street, Room 821, Denver, CO 80203 P 303.866.3581 F 303.866.3589 www.water.state.co.us Administrative Statement: Storm Water and Post-Wildland Fire Facilities, DWR February 11, 2016 Page 3 of 5 taking enforcement action in the event that the above criteria are not met in design and/or operation. To satisfy the notification requirement, operators are encouraged to use the Colorado Stormwater Detention and Infiltration Facility Notification Portal developed by Urban Drainage and Flood Control District ("UDFCD"), located at: https: / / maperture.digitaldataservices.com/gvh/?viewer=cswdif. Types of detention Facilities contemplated under this statute include underground detention vaults, permanent flood detention basins,' extended detention basins,2 and full spectrum detention basins.3 Storm Water Best Management Practices4 (BMPs) not contemplated above, including all Construction BMPs and non -retention BMPs, do not require notice pursuant to SB- 212 and are allowed at the discretion of the Division Engineer. Green roofs are allowable as long as they intercept only precipitation that falls within the perimeter of the vegetated area. Green roofs should not intercept or consume concentrated flow, and should not store water below the root zone. BMPs that rely on retention, such as retention ponds and constructed wetlands, will be subject to administration by the State Engineer. Any detention facility that does not meet all of the statutory criteria described above, in design or operation, is subject to administration by the State Engineer. ' Flood detention basin: An engineered detention basin designed to capture and slowly release peak flow volumes to mitigate flooding (Urban Drainage and Flood Control, 2010). 2 Extended detention basin: An engineered detention basin with an outlet structure designed to slowly release urban runoff over an extended time period (Urban Drainage and Flood Control, 2010). 3 Full spectrum detention basin: An extended detention basin designed to mimic pre -development peak flows by capturing the Excess Urban Runoff Volume and release it over a 72 hour period (Urban Drainage and Flood Control, 2010). 4 Best management practice: A technique, process, activity, or structure used to reduce pollutant discharges in stormwater (Urban Drainage and Flood Control, 2010). 1313 Sherman Street, Room 821, Denver, CO 80203 P 303.866.3581 F 303.866.3589 www.water.state.co.us Administrative Statement: Storm Water and Post-Wildland Fire Facilities, DWR February 11, 2016 Page 4 of 5 Post-Wildland Fire Facilities Pursuant to section 37-92-602(8), a post-wildland fire facility is a facility that: • Includes a structure or series of structures that are not permanent. • Is located on, in or adjacent to a nonperennial streams. • Is designed and operated to detain the least amount of water necessary, for the shortest duration of time necessary, to achieve the public safety and welfare objectives for which it is designed. • Is designed and operated solely to mitigate the impacts of wildland fire events that have previously occurred. In addition, to qualify for the allowances provided in SB-212, the facility: • Must be removed or rendered inoperable after the emergency conditions created by the fire no longer exist, such that the location is returned to its natural conditions with no detention of surface water or exposure of ground water. • Must not use water detained in the facility for any other purpose nor release it for subsequent diversion by the person who owns, operates, or has oversight over the facility. The facility will not be operated as the basis for a water right, credit, or other water use right. If the post-wildland fire facility meets the requirements listed above, it does not cause material injury to vested water rights. While DWR recognizes that post-wildland fire facilities are essential to the protection of public safety and welfare, property, and the environment, DWR may, from time to time, request that the person who owns, operates, or has oversight of the post-wildland fire facility supply information to DWR to demonstrate they meet the criteria set forth above. If a post-wildland fire facility does not meet all the criteria set forth above, it will be subject to administration by the State Engineer. 5 DWR may use the National Hydrography Dataset or other reasonable measure to determine the classification of a stream 1313 Sherman Street, Room 821, Denver, CO 80203 P 303.866.3581 F 303.866.3589 www.water.state.co.us Administrative Statement: Storm Water and Post-Wildland Fire Facilities, DWR February 11, 2016 Page 5 of 5 Resources and References Colorado Stormwater Detention and Infiltration Facility Notification Portal: https://maperture.digitaldataservices.com/gvh/?viewer=cswdif Colorado Senate Bill15-212: http: / /www.leg.state.co.us/CLICS/CLICS2015A/csl.nsf/fsbillcont3/13B28CF09699E67087257DE80 06690D8?Openatfile=212_enr. pdf United States Geological Survey National Hydrography Dataset: http://nhd.usgs.gov/ Urban Drainage and Flood Control District 37-92-602(8) explanation memo and FAQ's: http://udfcd.org/crs-37-93-6028-explanation-memo-and-faqs/ Urban Drainage and Flood Control District.
