I presented my credentials to Mr. Joshua Silva and Mr. Marcos Ocanas and informed them that this was an EPA inspection to determine the facility's compliance under the Clean Water Act (CWA) and the requirements of the National Pollutant Discharge Elimination System (NPDES) permit program, in accordance with the CWA. The generation of this report is based on information supplied by Los Alamos County representatives, observations made by the EPA inspector, NMED, and records and reports maintained by the permittee (Los Alamos County), and the EPA. It should be noted the Bayo-Compost facility, used in conjunction with the Bayo WWTF (NM0020141) also maintains a discharge permit (DP-1894) issued by the NMED, Groundwater Quality Bureau (GWQB) that allows a permitted discharge up to 3,000 gallons per day (gpd) of stormwater into a storage impoundment for evaporation or disposal offsite. FACILITY DESCRIPTION The Bayo-Compost facility is located at 3500 Pueblo Canyon Road, Los Alamos, in Section 18, T19N, R07E, Los Alamos County (denoted in Aerial Image #1 below). Groundwater most likely to be affected is at a depth of approximately 41 feet below land surface (BLS) and had a pre-discharge total dissolved solids concentration of 564 milligrams per liter (mg/L). The Bayo-Compost Area Expansion Project will fundamentally consist of two (2) phases, with the 1st phase consisting of fill placement, grading, liner installation, pond expansion, and concrete rundown. The 2nd phase will consist of placing and compacting a soil wear surface on top of the liner. 2 Los Alamos County/Bayo-Compost Expansion Permit No. NMR1005W6 Inspection Date 03/27/2024 Aerial Image #1: Overall view of the Los Alamos-Bayo Compost Facility. 2024 Aerial from Google Earth maps. Section II - OBSERVATIONS The following points of discussion are derived from review of information provided by Los Alamos County representatives, their consultant, or visual observation. Note: the entire Bayo Compost Expansion Stormwater Pollution Prevention Plan (SWPPP), inclusive of the rain fall and inspection logs were reviewed, for completeness and accuracy. There is some confusion as to Caldon Seeding and Reclamation, LLC, and their preparation of the SWPPP, their association to Dub-L-EE as the project operator (day-to-day control) and Los Alamos County as the Project Owner (Appendix 1 - DUB-L-EE, LLC SWPPP "Bayo Compost Expansion"). The Dub-L-EE, Notice of Intent (NOI) (NMR1005W6) cited in the Integrated Computer Information System (ICIS) indicates a Project Start Date of September 28, 2023, and a Project End Date of December 29, 2023. Additionally, the NOI states the "Estimated Area to be Disturbed as 1-acre". However, denoted on the Map Unit Legend associated with the United States Department of Agriculture-Natural Resources Conservation Service (USDA-NRCS) Soil Map-Santa Fe County Area (Bayo Compost Area Expansion) included in the SWPPP the "Acres in the Area of Interest" is listed as 4.8-acres. (Appendix 1 - DUB-L-EE, LLC SWPPP "Bayo Compost Expansion" and Appendix 2 - Dub-L-EE Notice of Intent). 3 Los Alamos County/Bayo-Compost Expansion Permit No. NMR1005W6 Inspection Date 03/27/2024 The enclosed SWPPP "Letter of Designation" is unsigned. See page 7 of 50 (Appendix 1 - Dub-LEE, LLC SWPPP "Bayo Compost Expansion"). The SWPPP states "When applicable, appropriate controls and measures will be implemented for each of the following major construction activities: a. Excavation: Wattle will be installed where indicated and at a minimum below discharging slopes to prevent "silty" storm water run-off from leaving the site. Wattle will also be installed at any possible discharge points. b. Pouring of concrete; curbs, drives, sidewalks, footings and or pads: If necessary, prior to pouring concrete, a concrete/concrete-masonry washout area must be constructed. A review of the submitted SWPPP Site Plan (labeled "TESCP") denotes an individual location of a "wattle at swale" but does not delineate the date of installation, or length. Additionally, referring to item b. above, a concrete wash-out area is not indicated. Note: The acronym "TESCP" is defined as Temporary Erosion and Sediment Control Plan. (Appendix 3 - SWPPP Site Plan "TESCP"). The enclosed United States Department of Agriculture-Natural Resources Conservation Service (USDA-NRCS) Soil Map-Santa Fe County Area (Bayo Compost Area Expansion) indicates staged sludge material, windrows, but it is unknown whether these have been stabilized to prevent vagrant dust or not. A review of the SWPPP states, "Temporary Stabilization (2.2 Stabilization Practices): Also see temporary erosion and sediment control drawing[s] Installation of Wattle as perimeter protection and at identified sediment discharge areas. In addition to Wattle at discharge locations, tackifier will be used if any areas that are left exposed for more than seven (7) days. Tackifier (plantago based m-binder) at manufacturer recommended amounts of 200 lbs per acre will be sprayed on all dormant areas. The referenced drawings were not enclosed or attached. (Appendix 1 - Dub-L-EE, LLC SWPPP "Bayo Compost Expansion"). A review of several of the Stormwater Construction Site Inspection Reports contain similar statements without validation of the corrective actions taking place. (Appendix 4 - Stormwater Construction Site Inspection Reports). Section III - SUMMARY/AREAS OF CONCERN The entire evaluation can be summarized as follows: There is some confusion as to Caldon Seeding and Reclamation, LLC, and their preparation of the SWPPP, their association to Dub-L-EE as the project operator (day-to-day control) and Los 4 Los Alamos County/Bayo-Compost Expansion Permit No. NMR1005W6 Inspection Date 03/27/2024 Alamos County as the Project Owner (Appendix 1- DUB-L-EE, LLC SWPPP "Bayo Compost Expansion").

The 2nd phase will consist of placing and compacting a soil wear surface on top of the liner. The project is located in Los Alamos, NM. There will be grading, concrete work, soil compaction, and finish work. Soil disturbing activities will include but are not limited to: rough grading, sub excavation, and installation of erosion and sediment control measures. 1.5 Site Map/General Location Map[s]/Areas of Soil Disturbance/Rainfall intensity See next page for location of project, soil mapping, precipitation data. 1.6 Scope of Work to be Completed The construction activities will consist of: Item Installation of BMPs Clearing and Grubbing Grading/Excavation Concrete Liner Installation Finish Work Final Grading/soil placement Final stabilization Begin End 1.7 Measures to Prevent Pollutant Discharge into Waters of the US It is the intent of the Owner/Operator and Contractor/Operator to provide and comply with permitted coverage requirements until 70% of the original vegetated state [prior to disturbance] of the area is evenly stabilized back to an original non-disturbed vegetated percentage. At such time, this SWPPP will be amended to reflect the termination of coverage and a Notice of Termination [NOT] will be filed. Required temporary erosion and sediment control devices will be installed prior to the commencement of construction activities on the Bayo Compost Area Expansion Project to prevent and control soil loss. While construction activities are occurring within the project; the appropriate control measures will be implemented by the operators in areas of soil disturbance to direct runoff and ensure that the transport of pollutants and sediment are minimized during storm water events. As the project is developed [progresses toward completion or in the event of rain] the entire project will be evaluated by inspection to determine and ensure that the appropriate control measures[s] are being utilized at each location or within certain areas.

Excavation: Wattle will be installed where indicated and at a minimum below discharging slopes to prevent "silty" storm water run-off from leaving the site. Wattle will also be installed at any possible discharge points. b. Pouring of concrete; curbs, drives, sidewalks, footings and or pads: If necessary, prior to pouring concrete, a concrete/concrete-masonry washout area must be constructed. This washout consists of excavating or berming a hole approximately 7'x7' square and approximately 3' deep. Once hole is excavated, line with a plastic sheet. When washout fills to 50% capacity, contractor is required to remove material and dispose of properly at a controlled or designated landfill. Actual location is anticipated near major structure placement. Placement is to be accessible location and will be modified as lane closures and work progresses. It is anticipated the majority of residual concrete that is left can be transported and returned by the delivering vehicle. Alternatively, a 10'x10' concrete washout can be constructed using 18 inch compost socks. c. Installation of any or all erosion or sediment control devices within the project or proposed phase: Temporary control practices will be utilized during the installation and construction of any or all infrastructure placement, including permanent sediment control devices. After sediment control devices have been installed and permanent controls [i.e. temporary sediment ponds or basins applied], temporary measures may or will be removed, if no longer required. d. Installation of temporary and permanent storm water/drainage structures: Maintain Wattle throughout the project, as needed. Follow manufacturer's guidelines for Wattle, generally when Wattle is filled to 50% with sediment, remove sediment. e. Installation of underground utilities: Reference [a] and [b] above. f. Complete final planting and seeding [landscaping] of disturbed areas (see re- vegetation plan paragraph 2.12): At a minimum, the entire site must be evenly stabilized to 70% of original non-disturbed vegetated condition before the owner can prepare and submit the Notice of Termination [NOT]. Temporary seeding/mulch or soil polymer will be used in exposed areas, not constructed and with no activity for a period of 14 days or greater or by permanent stabilization [prior to filing NOT] stabilize by seeding, mulching in areas not covered by permanent structures such as: paving, buildings, concrete, etc. No seeding expected. g. The Safe Drinking Water Act will be adhered to for this project - will not use any listed controls. After final construction, remove unnecessary temporary sediment control devices and stabilize area per [f] above. All control measures will be implemented as soon as it is practical and within 14 days of work cession within locations where construction activities have temporarily or permanently ceased. Bayo Compost Area Expansion 8 Storm Water Pollution Prevention Plan Caldon Seeding and Reclamation, LLC Control measures may be needed [or implemented] on certain portions of a site where the total time period that construction activity is temporarily ceased for less than 14 days [reference [c] above].

In addition to Wattle at discharge locations, tackifier will be used if any areas that are left exposed for more than 7 days. Tackifier (plantago based m-binder) at manufacturer recommended amounts of 200 lbs per acre will be sprayed on all dormant areas. Permanent Stabilization: Native seed (revegetation) will take place to permanently stabilize project area once work ceases or areas not covered by permanent stabilization (time noted on schedule). Otherwise the site will consist of impervious pavement/structure. Dub-L-EE, LLC has final stabilization responsibility. No seeding expected. Structural Practices [BMP Selection and Description(s)]: Note: Selection and preference of use, of site-specific BMP's follows industry standards and acceptability conforming to loading capacities and durability. Storm Water Management: Permanent seeding, landscaping and/or permanent stabilization will also take place in outlined/disturbed areas. None expected. Waste Materials: All waste materials will be collected and stored in a secure area. All trash and construction debris will be deposited in a dumpster or other containment. Dumpster should be emptied at least once per week or as required. Hazardous Waste: All hazardous waste materials will be disposed of in the manner specified by local or state regulations or by manufacturer. All sanitary waste will be collected from the portable units as required. Offsite Vehicle Tracking: A stabilized construction entrance may be installed to help reduce vehicle tracking of sediments. Initially, no entrance will be established and vehicles will be discouraged from entering worksite. A designated parking area will be established. Post Construction: Seeding and/or permanent stabilization will aid in stabilizing the project once work is complete, if needed. 2.3 Allowable Non-Storm Water Discharges [CGP] The following are authorized allowable non-storm water discharges, provided the non-storm water component of the discharge is in compliance with [Non-Storm Water Discharge Management]. Likely on this project (Yes or No) __N___ 1. Discharges from fire fighting activities Bayo Compost Area Expansion 12 Storm Water Pollution Prevention Plan Caldon Seeding and Reclamation, LLC __N___ - Fire fighting activities and requirements are an unforeseen element but are an essential component and necessity. Outlined in this SWPPP are BMP requirements to slow, channel, confine and filter sediment during construction, therefore limiting contaminated water from departing the project area. 2. Fire hydrant flushing - Hydrant flushing activity generally is captured for the benefit and reuse as project water for general construction purposes and not allowed to free run, allowing erosion and offsite travel of excess sediment. Continued water drought predictability or probability continues to be of concern. Water conservation is and will be a management criterion for this project with reuse for compaction or air quality dust control. ___N__ 3. Waters to wash vehicles where detergents are not used. - Washing of any vehicles or equipment is prohibited and will be conducted in areas offsite that are managed with containment and permitted by others. ___Y__ 4. Water used to control dust in accordance with Subpart 3.4.G - Offsite tracking is addressed within this SWPPP and will include a regiment of: - Street cleaning for prevention of dust by traffic [i.e. brooming or scraping off] as any visible aspect requires attention. - Dust control by watering and wetting with excess or erosion with reusable uncontaminated or potable dischargeable water. __N___ 5. Potable water including uncontaminated water line flushing - Project construction - If the potable water has chlorine in it, it should not be being used in this manner without proper controls per section 2 & 3. - Dust control ___N_ 6. Routine external building wash down that does not use detergents - N/A to this project __N___ 7. Pavement wash waters where spills or leaks of toxic or hazardous materials - Have not occurred [unless all spilled material has been removed] and where detergents are not used. __N___ 8. Uncontaminated air conditioning or compressor condensation - N/A to this project __N___ 9. Uncontaminated ground water or spring water - This project has no identifiable ground water or spring waters within project boundaries. In the event any such conditions arise and are identified, this SWPPP will immediately be amended with BMP's and management controls to accurately prevent contamination. This SWPPP has BMP's designated to prevent and reduce sediment-laden water from discharging and carrying offsite to any potential groundwater's or spring waters. Bayo Compost Area Expansion 13 Storm Water Pollution Prevention Plan Caldon Seeding and Reclamation, LLC ___N__ 10. Foundation or footing drains where flows are not contaminated with process materials such as solvents. ___N__ 11. Uncontaminated excavation dewatering __N___ 12. Landscape irrigation - Irrigation of landscaping is by design metered and controlled therefore not allowing excess discharge or runoff. Allowable Storm Water Discharges [CGP] The following are authorized allowable storm water discharges, provided the storm water component of the discharge is in compliance with [Non-Storm Water Discharge Management]. 1. Storm water associated with large and small construction activity as defined in Appendix A. 2. Storm water discharges designated by the EPA as needing a storm water permit under 40 CFR 122.26(a) (1) (v) or 122.26(b) (15) (ii) 3. Discharges from support activities [e.g., concrete or asphalt batch plants, equipment staging yards, material storage areas, excavated material disposal areas, borrow areas] provided: - The support activity is directly related to the construction site required to have a NPDES permit coverage for discharges of storm water associated with construction activity. - The support activity is not a commercial operation serving multiple unrelated construction projects by different operators, and does not operate beyond the completion of the construction activity at the last construction project it supports. - Appropriate controls and measures are identified in the Storm Water Pollution Prevention Plan [SWPPP] covering the discharges from the support activity areas. 4. Discharges composed of allowable discharges listed in 1.3.A. and 1.3.B commingled with discharge authorized by a different NPDES permit and/or a discharge that does not require NPDES permit authorization. Allowable storm water discharges are addressed as components of this SWPPP. Bayo Compost Area Expansion 14 Storm Water Pollution Prevention Plan Caldon Seeding and Reclamation, LLC 2.4 Potential Sources of Storm Water Pollution Inventory of potential sources of contamination: Construction activities have been determined to create significant sources of storm water Contaminants. The following have been identified as potential sources of storm water contamination. - Areas of significant soil erosion o Slopes greater than 3:1 o High velocity run-off channels - Storage and maintenance areas for material handling equipment; - Immediate access roads - Material handling sites [storage loading, unloading, transportation, or, conveyance of any raw material, finished product, intermediate product, by-product or waste] - Shipping and receiving areas - Equipment storage - Refuse sites - Disposal or application of wastewater [i.e. well drilling waste-water] - Areas containing residual pollutants from past industrial activity, spills and leaks - Vehicle maintenance and cleaning areas - Human/animal waste - Wind 2.5 Area/Equipment Tasks Frequency Preventive Maintenance/Inspections INSPECTION REPORTS ARE LOCATED AT THE END OF THIS TAB (rainfall amounts will be recorded on inspection reports) Preventative maintenance involves the regular inspection, testing and cleaning of project equipment and operational systems. These inspections will help to uncover conditions that might lead to a release of contamanants. This allows for preventative maintenance issues to prevent such release. The following equipment/activities will be included in the preventative maintenance program. The Operator shall continually [during scheduled and unscheduled specific site visits] monitor the implemented temporary erosion and sediment control measures during site-specific and project construction activities to ensure the effectiveness and operation condition of the measures. If changes or repairs are needed to improve the effectiveness and operation of a sediment control measure, changes or repairs will be implemented as soon as practicable. In no case shall the discovery of needed corrective action be greater than 7 days. Maintenance of temporary erosion and sediment control measures will continue until disturbed areas within the project have been stabilized. After the completion of construction activities maintenance measures will be performed when inspection finds it necessary to remove all silt accumulation or repair deteriorated or damaged structures. Any area detention ponds will be excavated when they lose 50% or more of their design capacity. Bayo Compost Area Expansion 15 Storm Water Pollution Prevention Plan Caldon Seeding and Reclamation, LLC The Owner/Operator will provide qualified personnel or companies to inspect disturbed areas of the project. Areas exposed to precipitation such as topsoil stockpiles and non-final stabilized areas will be inspected. Inspections will ensure measures are properly installed or applied and effective. The Owner/Operator is required to conform to the NPDES requirements, and is required [as the SWPPP requires] to verify that all contractors on this site complete and file a NOI and comply with this SWPPP or originate their own SWPPP. Any sub-contractors working under the directional control of a site operator will sign and participate in the SWPPP or be subject to compliance provisions. All temporary erosion and sediment control structures, measures, practice locations, and site vehicle access [enter and exit] points will be inspected every 7 days and within 24 hours after a storm water event of inch or greater. Inspectors will document sediment accumulation and if necessary recommend that corrective measures be implemented immediately. If emergency repairs and measures are needed after a significant rainfall [greater than inch], such measures and repairs will be performed and completed immediately and before the next significant rainfall event [if weather, supplies/materials and site conditions will permit]. Final stabilized areas and sites will be inspected every 14 days per the NPDES requirements effective February 16th, 2022 until the "NOT" is submitted. Inspectors will ensure control measures are maintained in good operating condition. The Operator [qualified personnel] will inspect disturbed areas and structures for erosion and sediment control effectiveness and for the potential of pollutants entering the drainage system. All erosion and sediment control measures not including final stabilization will be inspected and observed to ensure proper operation. Discharge locations will be inspected to assure effectiveness. Inspections will document effectiveness of measures and potential impacts to receiving waters. The Operator will modify/amend the SWPPP after an inspection has identified that a significant change is needed in the site/project [construction activities have been planned and identified or additional areas requiring temporary erosion and sediment control measures has been discovered]. Controls will then be incorporated into the plan at this location. If necessary, the SWPPP will be amended within seven days following an inspection's discovery of needed measures and action[s] to disturbed or other eroding areas [caused by construction activities] within the project. An amended NOI will be submitted at least two days prior [unless immediate action is required] to the commencement of construction activities at new location[s] which add new disturbed area, and plan amendments will be incorporated prior to the submittal of the amended NOI. The Operator will assure that the report is prepared and the inspection conducted by qualified personnel. The inspection report will summarize the inspection and shall contain the date of the inspection, findings, major observations, and certify project compliance with SWPPP and permit. If recommendations for actions are made, corrective measures shall be implemented. The SWPPP will be amended if necessary. Also, the inspection report will identify, describe and contain any incidents of non-compliance. The project Operator [or designated qualified personnel] will sign the inspection report and must comply with the signatory requirements set forth in the Construction General Permit [CGP]. All NPDES documents associated with this project will be kept for three years after the date on the Notice of Termination ["NOT"]. Bayo Compost Area Expansion 16 Storm Water Pollution Prevention Plan Caldon Seeding and Reclamation, LLC The Operator will ensure that non-storm water discharges do not cause sediments or pollutants to be discharged to receiving waters. Non-storm water discharges are not planned or expected to take place during the construction activities for the project, other than that exempt by the NPDES Program and this permit [i.e. dust control]. Other exempt non-storm water discharges that could possibly occur within the project during construction include flows from washing of vehicles [without detergents] or dust control. Changes in construction activities that produce non-exempt non-storm water discharges will be identified and the SWPPP will be amended and the appropriate temporary Erosion and sediment control measures will be implemented. 2.6 Good Housekeeping Good housekeeping practices are designed to maintain a clean and orderly work environment. This will reduce the potential for significant material to come in contact with storm water. The following practices are included in our good housekeeping routine: The contractor and subcontractors will use Best Management Practices [BMP's] and general common sense to limit contact between potential pollutants [chemical and other materials] and storm water. A designated parking area will be established, a construction yard will be designated on the Temporary Erosion and Sediment Control Drawing[s] and all temporary bathroom facilities will be located in this area. It is recommended clean rock or gravel be applied in this area to keep possible contaminants contained within this area. This also allows for the ease of cleanup should a spill occur. The contractor and subcontractors will implement good housekeeping practices by maintaining a clean and orderly construction site. BMP and good housekeeping practices will be utilized for: materials management; waste disposal; off-site tracking; spill prevention and response; sanitation; and non-storm water discharges: Contractor and subcontractor practices will include: - Materials Management: the proper handling and storage and labeling of chemicals and other potentially hazardous or toxic materials. A complete set of Material Safety Data Sheets [MSDS] sheets should be kept and maintained onsite for information purposes. Service vehicles shall be equipped with an emergency spill kit; materials will be stored and labeled within the designated staging area and potential hazard materials [i.e. paint, stucco, oil, grease, etc.] be placed on crates or pallets and protected. - Waste Disposal: the disposal of excess materials and solid waste to off-site locations designated as acceptable disposal sites for such materials. The removed material should be disposed of according to local rules and regulations covering hazardous waste. - Off-site Tracking: minimized by requiring vehicles to park in stabilized areas and periodic [once a week or as needed] watering of exposed areas. Should sediment be tracked onto adjacent roadways, a power broom will be used to sweep sediment back Bayo Compost Area Expansion 17 Storm Water Pollution Prevention Plan Caldon Seeding and Reclamation, LLC onto the jobsite, or sediment can be hand shoveled or broomed from roadway back onto the site. - Spill Prevention and Response: the discharge or spill of hazardous substances is not expected to occur due to or during construction activities. The project and its activities are not expected to use any substance in a manner or quantity that might require the reporting of a release in excess of reportable quantities. However, in the event that some unforeseen incident [spill of hazardous material in excess of reportable quantities] was to occur within the project during construction activities, the following measures will be followed: 1. The operator will: a) Stop the source of the spill b) Contain the spill c) Clean up the spill d) Dispose of material contaminated by the spill in an environmentally approved disposal site 2. Notify both the National Response Center (1-800-424-8802) and the New-Mexico Environment's Hazardous and Radioactive Materials Bureau (1-505-827-4300) within 24-hours of a release of hazardous materials in excess of reportable quantities 3. The operator will submit within 14 calendar days of the notification a description of the incident to the appropriate authorities; the operator will modify the SWPPP, if appropriate, within 14 calendar days of the notification and identify measures to prevent a reoccurrence. - Sanitation: providing temporary facilities [such as portable restrooms] to ensure that the site sanitation requirements comply with federal, state and local regulations. Anchor and place away from areas prone to activity or areas that could potentially carry a spill in the event of an accident. 2.7 Spill Control Practices In addition to good housekeeping practices discussed in this SWPPP, the following practices will be followed for spill prevention and cleanup: - Manufacturers recommended methods for spill cleanup will be clearly posted and site personnel will be made aware of the procedures and the location of the information and cleanup supplies. - Materials and equipment necessary for spill cleanup will be kept in the material storage area onsite. Equipment materials will include but are not limited to: brooms, dust pans, mops, rags, gloves, goggles, cat litter, sand, saw dust as well as plastic and metal trash containers specifically for this purpose. - All spills will be cleaned up after discovery. - The spill area will be kept well ventilated and personnel will wear appropriate protective clothing to prevent injury from contact with a hazardous substance. Bayo Compost Area Expansion 18 Storm Water Pollution Prevention Plan Caldon Seeding and Reclamation, LLC - Spills of toxic or hazardous material will be reported to the appropriate state or local government agency, regardless of size.

Rationale for BMP's In this Temporary Erosion and Sediment Control drawing[s] Wattle was included in the sediment yield analysis. Wattle was considered as the major component due to the effectiveness for sediment control and the ease of use at the construction site. 2. BMP Design and Construction Specifications The primary overall design specification for this BMP to be used in this project is that the listed BMP must be designed so as to reduce the construction phase sediment yield from the project to a level at or below the pre-construction undisturbed condition. The specifications are provided in the form of construction details and notes shown within the SWPPP documentation. 3. Maintenance Schedule and Inspection Criteria The maintenance and inspection criterion for the BMP's to be used during construction is given in the SWPPP documentation. Inspection, maintenance and rain event forms are provided in the SWPPP that need to be completed to ensure the effectiveness of the required project BMP's. After construction is complete [70% of the original natural vegetated state is substantially complete for the NOT execution], sediment control is achieved primarily by stabilization practices as opposed to structural practices. 4. BMP Performance and Longevity Given proper installation and maintenance, the BMP specified in the SWPPP documentation and analyzed herein are expected to perform at least as well as predicted by this analysis. Again, given proper maintenance as required by the SWPPP for operator performance during construction the longevity of the BMP's are expected to be equal to the duration of this project. 5. Conclusion The RUSLE equation and sediment yield analysis indicates that compost Wattles will be effective in controlling the sediment yield [travel] during construction of this project. It is anticipated that the sediment yields [travel] after construction will be similar to yields under existing conditions and implementation of the BMP's will lessen sediment runoff after construction. Rainfall intensity and Frequency charts included after page 6 were used to calculate the RUSLE output. The during and post construction will have a lower RUSLE factor due to grading and improved velocity dissipating devices. Bayo Compost Area Expansion 20 Storm Water Pollution Prevention Plan Caldon Seeding and Reclamation, LLC 2.9 Pollutants from Support Activities (Asphalt/Concrete Plants) There are no anticipated or potential impacts related to support activities from asphalt or concrete plants. Required materials are to be generated/produced and supplied by sources outside and away from project area. Others permit these sites and are required to comply with NPDES regulations. 2.10 Potential Pollutants Used and/or Found Onsite The following potential pollutants were evaluated for this project and whether or not they have a potential to affect storm water discharge from the job site. Including but not limited to: Pollutant Activity Oil Potential Effect Maintenance activity/Operations Grease Potential Effect Maintenance activity/Operations Ethylene Glycol Potential Effect Vehicle use/maintenance Petroleum Hydrocarbons Potential Effect Vehicle use/maintenance Suspended Solids Potential Effect Grading activities Dissolved Solids Potential Effect Grading activities Turbidity Potential Effect Grading activities Trash (wood, paper, cigarettes, ash, etc) Potential Effect General operations Fecal Coliforms (human/animal) Potential Effect Portapotty use Tar Potential Effect Paving Ops (n/a) Asphalt Potential Effect Curb/Gutter (n/a) Cement Potential Effect Curb/Gutter (n/a) Glues Potential Effect Finishing activities Solvents Potential Effect Paving Ops/Maintenance Metals Potential Effect Operations Chlorine in Potable Water Potential Effect Operations/Line flushing 2.11 Runoff Coefficient and RUSLE Calculations See attached sediment control calculations and figures for: - Pre existing sediment basins [pre construction] - Bare ground sediment basins [during construction] - Urban sediment basins [post construction] Total Area and Area of Disturbed Soil/Sediment Control Flow Calculations The project is subject to the requirements of the EPA Region VI General Permit. The project will utilize an NPDES permit [NMR1005W6] from the EPA and implement a SWPPP with Best Management Practices [BMP's] during construction activities to prevent and reduce pollutants and construction site run-off, due to activities performed, from leaving the project site during storm events. The SWPPP includes BMP's with temporary and permanent measures to prevent and reduce pollutants from leaving the project. The temporary erosion and sediment control measures Bayo Compost Area Expansion 21 Storm Water Pollution Prevention Plan Caldon Seeding and Reclamation, LLC identified in this plan will be observed by project operators and contracted consultants to ensure measures are effective in preventing impacts to the receiving watershed. See next page for calculations. 2.12 Revegetation plan Seeding will be completed on all disturbed areas not covered by base course, concrete, or other permanent stabilization. There is no seeding expected as the project. If necessary, Seeding will follow LAC seeding specifications and will consist of preparation of soil and hydroapplying a native seedmix and covered with 2,000lbs/ac hydromulch.

The U.S. Fish and Wildlife Service (Service) has responsibility for certain species of New Mexico wildlife under the Endangered Species Act (ESA) of 1973 as amended (16 USC 1531 et seq.), the Migratory Bird Treaty Act as amended (16 USC 701-715), and the Bald and Golden Eagle Protection Act as amended (16 USC 668-668(c)). We are providing the following guidance to assist you in determining which federally imperiled species may or may not occur within your project area, and to recommend some conservation measures that can be included in your project design. The enclosed species list identifies threatened, endangered, proposed and candidate species, as well as proposed and final designated critical habitat, that may occur within the boundary of your proposed project and/or may be affected by your proposed project. The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the ESA of 1973, as amended (16 U.S.C. 1531 et seq.). New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the ESA, the accuracy of this species list should be verified after 90 days. The Service recommends that verification be completed by visiting the IPaC website at regular intervals during project planning and implementation for updates to species lists and information. An updated list may be requested through the IPaC system by completing the same process used to receive the enclosed list. The purpose of the ESA is to provide a means whereby threatened and endangered species and 09/14/2023 2 the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the ESA and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat. A Biological Assessment is required for construction projects (or other undertakings having similar physical impacts) that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act (NEPA; 42 USC 4332(2) (c)). For projects other than major construction activities, the Service suggests that a biological evaluation similar to a Biological Assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a Biological Assessment are described at 50 CFR 402.12. If a Federal agency determines, based on the Biological Assessment or biological evaluation, that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service recommends that candidate species, proposed species and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found in the "Endangered Species Consultation Handbook" at https://www.fws.gov/sites/default/files/documents/ endangered-species-consultation-handbook.pdf. Candidate Species and Other Sensitive Species A list of candidate and other sensitive species in your area is also attached. Candidate species and other sensitive species are species that have no legal protection under the ESA, although we recommend that candidate and other sensitive species be included in your surveys and considered for planning purposes. The Service monitors the status of these species. If significant declines occur, these species could potentially be listed. Therefore, actions that may contribute to their decline should be avoided. Lists of sensitive species including State-listed endangered and threatened species are compiled by New Mexico State agencies. These lists, along with species information, can be found at the following websites. Biota Information System of New Mexico (BISON-M): www.bison-m.org New Mexico State Forestry. The New Mexico Endangered Plant Program: https://www.emnrd.nm.gov/sfd/rare-plants/ New Mexico Rare Plant Technical Council, New Mexico Rare Plants: nmrareplants.unm.edu Natural Heritage New Mexico, online species database: nhnm.unm.edu 09/14/2023 3 WETLANDS AND FLOODPLAINS Under Executive Orders 11988 and 11990, Federal agencies are required to minimize the destruction, loss, or degradation of wetlands and floodplains, and preserve and enhance their natural and beneficial values. These habitats should be conserved through avoidance, or mitigated to ensure that there would be no net loss of wetlands function and value. We encourage you to use the National Wetland Inventory (NWI) maps in conjunction with ground-truthing to identify wetlands occurring in your project area. The Service's NWI program website, www.fws.gov/wetlands/Data/Mapper.html, integrates digital map data with other resource information. We also recommend you contact the U.S. Army Corps of Engineers for permitting requirements under section 404 of the Clean Water Act if your proposed action could impact floodplains or wetlands. MIGRATORY BIRDS In addition to responsibilities to protect threatened and endangered species under the ESA, there are additional responsibilities under the Migratory Bird Treaty Act (MBTA) and the Bald and Golden Eagle Protection Act (BGEPA) to protect native birds from project-related impacts. Any activity, intentional or unintentional, resulting in take of migratory birds, including eagles, is prohibited unless otherwise permitted by the Service (50 CFR 10.12 and 16 USC 668(a)). For more information regarding these Acts, see https://www.fws.gov/program/migratory-bird-permit/ what-we-do. The MBTA has no provision for allowing take of migratory birds that may be unintentionally killed or injured by otherwise lawful activities. It is the responsibility of the project proponent to comply with these Acts by identifying potential impacts to migratory birds and eagles within applicable NEPA documents (when there is a Federal nexus) or a Bird/Eagle Conservation Plan (when there is no Federal nexus). Proponents should implement conservation measures to avoid or minimize the production of project-related stressors or minimize the exposure of birds and their resources to the project-related stressors. For more information on avian stressors and recommended conservation measures, see https://www.fws.gov/library/collections/threats-birds. We also recommend review of the Birds of Conservation Concern list (https://www.fws.gov/ media/birds-conservation-concern-2021) to fully evaluate the effects to the birds at your site. This list identifies migratory and non-migratory bird species (beyond those already designated as federally threatened or endangered) that represent top conservation priorities for the Service, and are potentially threatened by disturbance, habitat impacts, or other project development activities. In addition to MBTA and BGEPA, Executive Order 13186: Responsibilities of Federal Agencies to Protect Migratory Birds, obligates all Federal agencies that engage in or authorize activities that might affect migratory birds, to minimize those effects and encourage conservation measures that will improve bird populations. Executive Order 13186 thereby provides additional protection for both migratory birds and migratory bird habitat. Please visit https://www.fws.gov/partner/ council-conservation-migratory-birds for information regarding the implementation of Executive Order 13186. 09/14/2023 4 We suggest you contact the New Mexico Department of Game and Fish, and the New Mexico Energy, Minerals, and Natural Resources Department, Forestry Division for information regarding State protected and at-risk species fish, wildlife, and plants. For further consultation with the Service we recommend submitting inquiries or assessments electronically to our incoming email box at nmesfo@fws.gov, where it will be more promptly routed to the appropriate biologist for review. We appreciate your concern for threatened and endangered species. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act. Please include the Consultation Code in the header of this letter with any request for consultation or correspondence about your project that you submit to our office. Attachment(s): Official Species List OFFICIAL SPECIES LIST This list is provided pursuant to Section 7 of the Endangered Species Act, and fulfills the requirement for Federal agencies to "request of the Secretary of the Interior information whether any species which is listed or proposed to be listed may be present in the area of a proposed action".
