SUMMARY

1. PURPOSE: This plan is designed to provide Malmstrom AFB personnel with the following information:

a) Potential sources of pollutants in runoff from industrial and construction activity.

b) Best management practices to eliminate/reduce pollutants.

c) Organizations and individuals tasked in maintaining pollution control equipment or implementing best management practices.

2. CONDITIONS FOR IMPLEMENTATION: This plan is effective upon receipt and will be used in day-to-day operations.

3. OPERATIONS TO BE CONDUCTED: This plan identifies potential sources of runoff pollutants from industrial and construction activities that affect the quality of discharge, identifies best management practices to eliminate/reduce pollutants and tasks those organizations responsible for implementing those practices. In accordance with Part IV C of the General Permit, Discharges to Water Quality Impaired Waterways, MAFB has identified the MT41Q331_013, water class B-3, Missouri River from Rainbow Dam to Morony Dam as receiving surface water that is listed as impaired on the state’s 303(d) list. MAFB has actively sampled and reviewed for any potential impacts to the water body. This review has determined that other than sediment no pollutants of concern are discharged from MAFB to the impaired water body. The best management practices under permit authorization MTR000197 and MTR40008 (Small Municipal Storm Sewer General Permit) collectively control sediment and other pollutants of concerns in MT41Q001_01.

4. COMMAND RELATIONSHIP: All activities that affect the quality and operation of storm water pollution control practices or equipment.

5. OPSEC: Operations security considerations were used in preparing this plan.

6. This is an updated publication and supersedes all previous versions.

1. PURPOSE: This plan provides guidance, procedures, and actions taken by personnel or organizations that maintain pollution control equipment to reduce or eliminate pollutants entering the storm water system. This plan also implements the requirements of Permit MTR 000197, Authorization to Discharge, under the Montana Pollutant Discharge Elimination System, Section IV.

2. TASKED ORGANIZATIONS: All personnel assigned to organizations that have activities with a potential to discharge pollutants or undesirable substances to the storm water system are tasked to implement the best management practices (BMP) outlined in this plan. These activities include outdoor storage, loading and unloading of dry bulk material or liquids, and outdoor process activities. Specific organizational tasking identified in the list of activities that have the potential to discharge to the storm water system are in Annex A, Description of Potential Pollutant Sources. Compliance with this plan is mandatory.

3. SITUATION: 341st Civil Engineer Squadron Environmental Flight (341 CES/CEV) personnel prepared this storm water pollution prevention plan (SWP3) in accordance with AFI 32-7041, Water Quality Compliance, and state and federal storm water regulations under the Montana Pollutant Discharge Elimination System (MPDES) Phase I and permit MTR 000197. These regulations require identification of all potential sources of pollutants in runoff, inclusion of best management practices, site maps, and other detailed information specified in the MTR 000197 permit and regulation.

4. MISSION: The mission is to eliminate the effects of pollutants on the waters of Montana and to maintain compliance with the Clean Water Act and permit MTR 000197.

In accordance with Part IV C of the General Permit, Discharges to Water Quality Impaired Waterways, MAFB has identified the MT41Q331_013, water class B-3, Missouri River from Rainbow Dam to Morony Dam as a receiving surface water that is listed as impaired on the state’s 303(d) list . MAFB has actively sampled and reviewed for any potential impacts to the water body. This review has determined that the best management practices

BP-1

September 2006 under permit authorization MTR000197 and MTR40008 collectively control any pollutants of concern in MT41Q001_01.

5. EXECUTION:

5.1. Concept of Operations:

5.1.1. A comprehensive and standardized source of information and methods must be available to assist in accomplishing the plan’s mission because many activities at Malmstrom AFB that can affect storm water quality cross organization lines.

5.1.2. The primary source for guidance and reporting of storm water activities at Malmstrom AFB is 341 CES/CEV.

5.1.3. Each organization must be accountable for their activities because there are many activities performed outside of 341 CES that affect the storm water discharges.

5.1.4. Not all organizations or management practices may be implemented or affected by this plan.

5.1.5. This plan will be implemented for all activities identified in this plan.

5.2. Tasked Organizations:

5.2.1. The 341st Space Wing commander has responsibility for Malmstrom AFB storm water discharges, but delegates the authority to carry out the storm water management program to other individuals and organizations; i.e., the Environmental, Safety, and Occupational Health Council, which is chaired by the vice commander.

5.2.2. 341 CES/CEV is responsible for storm water issues. They are the focal point for all the technical aspects of the storm water program including the implementation, maintenance, and revision of the SWP3. It is also responsible for assessing storm water management practices and selecting those that are reasonable and appropriate for the installation. In addition, they must determine which BMPs to implement to reduce storm water contamination.

5.2.3. All squadrons are identified in Annex A.

3. OUTDOOR PROCESS ACTIVITIES:

3.1. WSA Vehicle Washing (341 SFG): Vehicle washing is allowed at the weapons storage area next to building 1867 in a grassy area. The washing operation has been limited to prevent wash water from entering a field storm drain inlet. The surrounding grassed area takes up rinsate from this operation.

3.2. Street De-icing and Sanding (341 CES/CEOHH): FreezGard Zero (magnesium chloride hexahydrate), has been applied to streets as needed for deicing since 1997. Sand is no longer used for street deicing.

3.3. Defense Reutilization Marketing Office yard (DRMO): DRMO disposes of excess property received from the military services throughout Montana and Idaho. The inventory changes daily and includes many items: from air conditioners to vehicles, clothing to computers, scrap metal and much more. Any item that can degrade with exposure to the elements is stored inside warehouses. Other items such as scrap metal, vehicles and tires are stored outside in specially designated cells with secondary containment or cover when appropriate. This paved yard discharges to a grassy swale that empties into an open channel that discharges off boundary.

3.4. Civil Engineer Compound (341 CES/CEO): This area lies directly east of Bldg 471.

There are numerous fenced lots that are used to store excess materials such as piping, scrap metal and appliances. These materials are stored until there is sufficient quantity to transfer to the DRMO yard. Storm water is discharged through inlets into the storm system.

A-6

Storm Water Pollution Prevention Plan September 2006

4. DUST OR PARTICULATE GENERATING PROCESSES

4.1. Bldg. 82110 - Central Coal-Fired Heating Plant (341 CES/CEOIP): The heat plant stores and transports coal as a fuel source. The coal is stored on a coal pad, which is concrete with storm drain inlet pipes, which transport runoff into a holding pond. The fly ash is stored in a hopper and approximately once a week is hauled out for disposal at a local landfill.

4.2. Construction Activities (341 CES/CEC): During the construction season, any number of construction or demolition projects occur on the installation. All projects that disturb one acre or more are required to obtain storm water construction permits. Project specifications also require erosion control plans. The responsible wing official must sign the notice of intent (NOI) and storm water protection plan (SWPP) before submittal to the Montana Department of Environmental Quality (MDEQ). Proper management of soil erosion and sediment is essential for construction projects that will disturb less than one acre to ensure compliance with the Clean Water Act. The selection of the best soil erosion and sediment controls for the site shall be based upon the nature of the construction and the conditions that exist at the site. The primary goals of soil control for construction projects are: 1) Prevent runoff from offsite areas from flowing across disturbed areas, 2) Slow down the runoff traveling across the site and 3) Remove sediment from onsite runoff before it leaves the site. For a listing of the construction BMPs employed at MAFB, see Annex P or contact the 341st CES Environmental Flight.

4.3. Gravel storage piles (341 CES/CEOHH and 819 RHS): Gravel, clean fill, and old asphalt are stored for re-use on an old abandoned runway in the southeast corner of the base. The area around the site is covered with prairie grass and has less than a 2% slope in any direction.

4.4. Landfarm for fuel contaminated soil (341 CES/CEV): The landfarm is located on the west portion of the old abandoned runway used to store gravel. The land farm is permitted by the MDEQ and has a one-foot earthen berm surrounding the entire site. The site is approximately 100 feet wide and 1,400 feet long.

4.5. Wood pile (341 CES/CEVV): The woodpile is located east of the RV storage area on Perimeter Road. Scrap lumber is stored in this area until sufficient quantity has accumulated to chip. The resulting mulch is then used for compost or trucked to the local landfill to be used for roads within the landfill. The area slopes to the center, therefore no run-off is associated with this activity.

4.6. Construction & Demolition Rubble yard (341 CES/CEO): This is central location for concrete and demolition rubble from various construction activities on the installation.

Most C&D rubble is contracted to be disposed of off-site in a licensed landfill, this area is for MAFB generated waste and for other small demolition projects. Once enough debris is collected, a contractor is procured to crush the debris for reusable material. Access is controlled by a locked gate and signs are posted on rules of use. Storm water flows through the site to grassy swales that discharge to Pow Wow Pond.

A-7

Storm Water Pollution Prevention Plan September 2006

5. ILLICIT CONNECTIONS: An illicit cross-connect survey was completed in 1996 by Thomas, Dean and Hoskins, a contracted consulting engineer. The study identified cross-connects in the following facilities.

Bldg. 122 - Proof Load Test Facility, Bldg. 349 - Crash and Structural Fire Station, Bldg. 870 - Vehicle Maintenance Shop, Bldg. 1192 - Family Services, Bldg. 1305 - Open Mess, Bldg. 1712 - Filter Separator Building and Bldg. 1840 – AS&I Building

Malmstrom has corrected all these cross connections.

6. WASTE DISPOSAL PRACTICES:

6.1. Power Production (341 CES/CEOIG) Bldg. 200: Used hydraulic fluid, sulfuric acid, lube oil, test fluid and antifreeze are stored for disposal.

6.2. Electric Shop (341 CES/CEOIE) Bldg. 407 (Satellite Accumulation Point): Lithium & Ni-Cad batteries and mercury vapor light bulbs are stored for disposal.

6.3. Central Hazardous Waste Accumulation Point (341 CES/CEVV) Bldg. 434: All wastes from satellite accumulation point areas are delivered to this storage yard for characterization.

6.4. AGE (341 MOS/MXOPA) Bldg. 450 (Satellite Accumulation Point): JP-8 fuel filters with benzene are stored for disposal. This facility will be moving to a new facility, Bldg 368 along with the Corrosion Control. Once the move has been completed this plan will be updated to reflect the change.

6.5. Vehicle Maintenance Shops (341 LRS/LGRVM) Bldg. 870 (Satellite Accumulation Point): Used oil and antifreeze are stored for recycling. Waste oil is stored in a 660 gallon AST.

6.6. Missile Maintenance (341 MOS/MXOPP) Bldg.1439 (Satellite Accumulation Point):

Sodium chromate solution with cadmium and battery acid are stored for disposal.

6.7. Helicopter Operations (40 OPG/HS) Bldg. 1440 (Satellite Accumulation Point):

Products used include diesel fuel, solvent, 2 butoxy-ethanol, lube oil, hydraulic fluid, paint thinner, JP-8, and methyl ethyl ketone (MEK). Waste materials are stored in the satellite accumulation point for disposal. Rags contaminated with solvents are the primary waste streams. The largest containers are 55-gallon drums, which are stored on spill pallets.

6.8. Defense Reutilization and Marketing Office (DRMO) Bldg. 1535 (Location of Treatment, Storage And Disposal Facility (TSDF)): All materials for sale and disposal are stored inside facility in specially designed cells.

6.9. Weapon Assembly Building (341 MMXS/MXMW) Bldg. 1840 (Satellite Accumulation Point): Materials stored in the facility include Mono-methyl Hydrazine (MMH) and Nitrogen Tetroxide (N204). In addition, small quantities of paints, oils, greases, adhesives and solvents are stored for daily use. Small quantities of low-level radioactive

A-8

Storm Water Pollution Prevention Plan September 2006 wastes and low-level radioactive mixed wastes are also generated. The small quantities of paints, oils, greases, adhesives, and solvents are stored in a flammable storage locker with a liquid tight 2-inch bottom well for secondary containment. Hazardous wastes derived from missile maintenance operations are stored in approved metal drum containers with locking rings inside an approved flammable locker designated for waste materials only.

6.10. MXS Corrosion Facility (341 MMXS/MXMEC) Bldg. 3065 (Satellite Accumulation Point): Various small amounts of hazardous wastes are stored in a room that has a three-inch high aluminum pan surrounding the containers. This facility will be moving to a new facility, Bldg 368 along with the AGE. Once the move has been completed this plan will be updated to reflect the change.

6.11. Central Coal Fired Heating Plant (341 CES/CEOIP) Bldg. 82110: Fly ash is stored in a hopper and periodically loaded in containers and trucked to the local permitted landfill.

6.12. Helicopter Maintenance 3-Bay Hangar (40 HF) Bldg 1440, Aqueous Film Forming Foam chemical (AFFF). The fire fighting chemical AFFF is made of: Diethylene Glycol Monobutyl Ether 209, Hydrocarbon Surfactants, Fluoro Surfactants, Inorganic Salts and water. AFFF commonly causes high BOD and foaming therefore this discharge is directed to a holding tank that controls final discharge to the sanitary sewer system.

6.13. Missile Transfer Building (341 MMXS/MXMNH) Bldg 1845: An AFFF system is installed with 400 gallons of AFFF (mixed 3% AFFF 97% water = 12,933 gallons liquid). This foam would enter a floor drain leading to a manhole and be pumped to a holding pond.

6.14. Landfills (341 CES/CEVR): There are two closed landfills on Malmstrom AFB.

One is northeast of the Weapons Storage Area (WSA). The Flightline Landfill is located off the northeast end of the runway northeast of perimeter road. Both of these landfills are Resource Conservation Recovery Act (RCRA) Solid Waste Management Units (SWMU). The landfills are neither capped (by RCRA standard) nor lined. The Flightline Landfill (SWMU SW-2) was used primarily for construction debris and rubble.

Corrective actions for SW-2 are complete. The landfill near the WSA (SWMU SW-3) was used for domestic waste and was operated under the applicable state standards during the time it was in operation. RCRA facility investigations were completed at both sites.

No contamination was found that posed a risk to human health or the environment at the Flightline landfill. Long term monitoring of surface water and subsurface water at the landfill northeast of WSA (SW-3) is underway. The U.S. Environmental Protection Agency, Region VIII Montana Office has given authority for these sites to the MDEQ and Malmstrom is required to manage these sites under the RCRA Corrective Actions Program.

3.1. The preventative maintenance program identifies equipment, systems, and facility areas that will be inspected. This program provides a schedule for inspections and tests, and addresses appropriate adjustment, cleaning, repair or replacement of devices, equipment, and systems. The preventative maintenance program requires timely inspections and maintenance of storm water management systems to discover any potential problems that could lead to the contamination of storm water. Equipment and systems requiring inspection are identified in the following sections.

3.1.1. Aboveground storage tanks (AST):

3.1.1.1. Fuel levels checked periodically. Fuel consumption records maintained and reviewed by the using organization.

3.1.1.2. Tanks will be inspected regularly upon refilling by Fuels Management.

3.1.1.3. Timely repair of leaking valves, lines, and tanks will be accomplished.

3.1.2. Underground storage tanks (USTs): There are 16 active tank systems on Malmstrom AFB. They include one single walled fiberglass UST, 12 double-walled fiberglass USTs, and four underground pipes with secondary containment that run from ASTs. A soil sentry communications interface program is used for interstitial monitoring in the double walled tanks and piping. The single walled tank is monitored using Arizona Instruments Inc. (AZI) automatic gauging. Timely repair of leaking valves, lines, and tanks is also practiced. All USTs are inspected by a third party contracted inspector for compliance with MDEQ requirements on a three-year cycle.

3.1.3. Sanitary sewer lift station: The lift station requires weekly inspections by the utility shop (341 CES/CEOFD) to ensure the pumps are in good working order and that there are no signs of leaks, overflows or other operational concerns.

3.1.4. Hazardous waste accumulation points: A visual inspection of accumulation areas for signs of leaking or damaged containers is done on a weekly basis, and the site manager must keep all records of inspection.

3.1.5. Hazardous materials storage areas: Items are managed on a first in, first-out basis to avoid expired shelf life. Inspections on a regular basis are required to ensure shelf life have not expired. In the case of expired shelf life, items either are turned in for disposal or are tested for use. Visually inspect storage areas on a regular basis for signs of leaking or damaged containers.

3.1.6. Loading and unloading areas: Individual facility managers are responsible for maintenance and housekeeping of these areas. Proper spill cleanup equipment will be maintained and readily available during loading and unloading operations.

3.1.7. Oil/water separators, catch basins, slide gates, and other structural best management practices.

3.1.7.1. All oil/water separators are the responsibility of the shop that utilizes them (See MAFB Instruction 32-7001).

3.1.7.2. An inspection that meets the requirements of the manufacturer at a minimum shall include a check of liquid levels and operation and maintenance requirements.

3.1.8. All storm water drain inlets, channels and slide gates are inspected by the horizontal section (341 CES/CEOHH) periodically through a reoccurring work order to ensure they are functioning properly.

3.1.9. Street Clean up: The horizontal section (341 CES/CEOHH) performs street sweeping approximately once a week. This practice reduces the total suspended solids (TSS) buildup in the storm water system.

3.1.10. Construction Best Management Practices (BMPs):

3.1.10.1. Prevent runoff from offsite areas from flowing across disturbed areas using methods such as the following: earth dikes, interceptor dikes and swales, drainage swales and pipe slope drains.

3.1.10.2. Slow down the runoff traveling across the site by: gradient terraces and surface roughing (e.g. permanent seeding, Geo-textiles, sod stabilization and mulching).

3.1.10.3. Remove sediment from onsite runoff before it leaves the site by using such things as: sediment traps, silt fences, gravel filter berm, sediment basins and inlet protection.

3.1.10.4. Keep vehicle tire treads from transferring soil from the job site to base roadways and storm system by using metal exit grates and daily street sweeping.

3.1.10.2. For additional information on construction BMP’s see EPA website at http://cfpub.epa.gov/npdes/stromwater/memuofbmps/con_site.cfm http://cfpub.epa.gov/npdes/stromwater/memuofbmps/con_site.cfm

SITE INFORMATION, OUTFALL AND DRAINAGE INFORMATION

1. SITE INFORMATION

1.1. Malmstrom AFB is located in north central Montana (latitude 47°31’ N, longitude 111°11’ W) about one mile east of the Great Falls city limits. The base consists of 3,260 acres and has restrictive easements on an additional 441 acres.

1.2. Located in a section of rolling plains about 75 miles east of the Rocky Mountains, Malmstrom AFB lies at an elevation of 3,525 feet above sea level on a plateau that slopes away from the Little Belt Mountains, north towards the Missouri River. The Missouri River flows north and northeast of the base. Stream valleys are interspersed throughout the area, but most of the year these valleys are dry. Any water runoff north of the flight line is directed into pipes, coulees or ditches that ultimately join one principle, but unnamed coulee (locally referred to as the Whitmore Ravine) that discharges into the Missouri River. Any water runoff south of the flight line is directed into coulees or ditches into Pow Wow Pond or exits the installation boundary via sheet flow. The greatest natural physical relief (40 to 50 feet) occurs in the northeast section of the base where runoff has carved a course through the glacial till.

2. SITE MAP

2.1. Appendix 1 to Annex R contains the MAFB storm water system map that delineates the base drainage areas, surface water bodies, discharge points, structural controls, facilities of concern, and the existing storm water system.

3. TOPOGRAPHIC MAP

4.1. Appendix 2 to Annex R contains copies of the USGS maps that delineate Malmstrom AFB. Appendix 2 to Annex R illustrates the surface water bodies, and the topography in and around MAFB.

4. DIRECTION OF FLOW

4.1. Outfalls 1 through 6 all have point discharges upstream in the storm sewer system.

The storm system for these outfalls flow north to the installation boundary then through easements to the unnamed coulee locally referred to as Whitmore Ravine. Figures R-1 and R-2 illustrate the drainage areas and the flow routes respectively.

Storm Water Pollution Prevention Plan

R-2

Figure R-1 – Drainage Areas located on Malmstrom AFB.

4.2. Drainage areas 7, 8 and 9 do not have a point discharge. Hence sampling of these drainages is not required. All the drainages on the installation that have point discharges travel across open farm land and eventually discharge into the Missouri River at a point approximately one mile north.

5. SAMPLE DATA

5.1. During the last permit term, October 2001-September 2006, Malmstrom AFB has sampled the five outfalls along the north boundary of the installation. This historic data is provided in Annex W to the Basic plan. Due to a re-evaluation by the Water Protection Bureau at the state of Montana is has been determined that only those facilities affected under the Administrative Rule of Montana Title 17 Chapter 30 Sub-Chapter 11 Section 1304(29) are required to sample. MAFB conducts one activity that is identified in Part IIIA.2., of the General Permit; Petroleum Storage and Fueling; that is required to conduct sampling pursuant to the General Permit . This activity is located in two separate areas of the installation, see Appendix 2 to Annex W-MAFB Sampling Locations for these locations. For sampled parameters see Annex W.

COMPREHENSIVE SITE INSPECTIONS

1. PURPOSE

1.1. The comprehensive site compliance evaluation is an annual inspection conducted by 341st Civil Engineer Squadron Environmental Flight (341 CES/CEVC). Material handling, storage areas, and other potential contributing areas are visually inspected for evidence of actual or potential pollutant discharges to the storm water drainage system.

Structural storm water management devices and pollution prevention equipment are also inspected to confirm their proper working order. The environmental flight documents the results of each inspection in a report signed by an authorized official as specified in the Montana Pollutant Discharge Elimination System (MPDES) permit. When new storm water pollutant sources are identified or existing sources are significantly altered, this plan shall be amended.

1.2. Areas must be inspected to:

1.2.1. Identify any evidence of or potential for pollutants entering the storm water drainage system.

1.2.2. Determine if measures to reduce pollutants loading are adequate and properly implemented.

1.2.3. Determine if additional controls are needed and if existing structural control measures are operating correctly.

1.2.4. Visually determine status of pollution prevention equipment (i.e., spill response equipment).

1.3. A compliance evaluation report will be prepared and retained as part of the storm water pollution prevention plan for at least 5 years after coverage of permit expiration.

The report must be signed in accordance with the regulatory signatory requirements as outlined in the MPDES permit. The report will discuss all items listed in Part IV.A.4 of the general permit, MT00197.

1.4. This report must be submitted to the Montana Department of Environmental Quality (MDEQ) by January 28th of each year.
