ABOUT THIS PLAN

This installation-specific Environmental Management Plan (EMP) was developed using the U.S.

Air Force’s (AF) standardized Stormwater Pollution Prevention Plan (SWPPP) template. This plan is not an exhaustive inventory of all stormwater requirements and practices. Where applicable, external resources, including Air Force Instructions (AFIs); Department Air Force

Manuals (DAFMANs); AF Playbooks; and federal, state, local, and permit requirements are referenced.

Each section of this BMP template begins with standardized, AF-wide “common text” language that addresses AF, Department of Defense (DoD), and federal requirements, including the

Environmental Protection Agency (EPA). This common text language is restricted from editing to ensure that it remains standard throughout all plans. The common text language is maintained and updated by the designated Office of Primary Responsibility (OPR) with assistance from the

Office of Collateral Responsibility (OCR), as appropriate. Immediately following the AF-wide common text sections are Installation sections. The Installation sections contain installation-specific content to address state, local, and installation-specific requirements. Installation sections are unrestricted and are maintained and updated by installation or Section personnel.

This document is optimized to be accessed and viewed electronically. The eDASH website at https://usaf.dps.mil/teams/eDASH/wpp/homepage/home.aspx is the primary communication tool for AF EMPs.

4.0 INDUSTRIAL SOURCE AREAS COVRED UNDER THIS BMP OVERVIEW

Industrial source areas for air transportation-related activities covered by Sector S performed at the Base include vehicle maintenance (including vehicle rehabilitation, mechanical repairs, painting, fueling, and lubrication), equipment cleaning operations, and deicing operations.

At the Base, these sector-specific sites include:

• Fueling and Refueling Areas;

• Aircraft Maintenance, Runways and Tarmac Areas;

• Aircraft, Vehicle, and Equipment Washing Areas; and

• Recycling, Hazardous Materials, and Waste Storage Areas.

Each of the activities, identified sector-specific industrial areas, and their associated BMPs are discussed below.

Numerous BMPs discussed in this BMP template are implemented in areas where industrial activities could impact stormwater.

5.0 CONTRACTOR ACTIVITIES

Information about contractor activities is required for the selection of proper BMPs. Details that should be recorded include:

• Equipment storage, cleaning, and maintenance areas and activities;

• Points of ingress and egress to the construction site;

• Material loading, unloading, and storage practices and areas, including construction materials, building materials, and waste materials; and

• Materials, equipment, and vehicles that may come in contact with stormwater.

Principles for Identifying and Selecting BMPs

The QSD selects BMPs. The contract between the owner and contractor should specify the responsibilities of the owner and contractor with regards to stormwater pollution control during construction. Owners must be aware that regardless of the contractual agreement between the owner and the QSD or the contractor with respect to BMP selection and implementation. Principles used to guide the selection of BMPs for construction activities are presented in the following sections. BMPs are generally selected in a three-step process:

• Define BMP objectives;

• Identify BMP category; and

• Select appropriate BMPs.

Define BMPs Objectives

Selection and implementation of BMPs is based on the pollution risks associated with the construction activity. Defining the pollution prevention goal is based on a review of information gathered during the assessment of the site and planned activities. Once defined, BMP objectives are developed and BMPs selected. The BMP objectives for construction projects are as follows:

• Control Erosion and the Discharge of Sediment:

• Control Site Perimeter: Delineate site perimeter to prevent disturbing areas outside the project limits. Divert upstream run-on safely around or through the construction project.

Local codes usually state that such diversions must not cause downstream property damage or be diverted into another watershed. Runoff from the project site should be free of excessive sediment and other constituents. Control tracking at points of ingress to and egress from the project site.

• Minimize Disturbed Areas: Phase clearing and grading to limit exposed area to that which can be protected; only clear land which will be actively under construction in the near term;

minimize new land disturbance during the rainy season; and avoid clearing and disturbing sensitive areas (e.g., steep slopes and natural watercourses) and other areas where site improvements will not be constructed.

• Stabilize Disturbed Areas: Provide temporary stabilization of disturbed soils for inactive portion(s) of the site. An inactive area is an area of the project that has been disturbed and is not scheduled to be re-disturbed for at least 14 days. Provide permanent stabilization during finish grade and landscape the site.

• Protect Slopes and Channels: Safely convey runoff from the top of the slope and stabilize disturbed slopes as quickly as possible. Avoid disturbing natural channels. Stabilize temporary and permanent channel crossings as quickly as possible and ensure that increases in runoff velocity caused by the project do not erode the channel.

• Retain Sediment: Retain sediment-laden waters from disturbed, active areas within the site.

• Manage Non-Stormwater Discharges and Materials:

• Practice Good Housekeeping: Perform activities in a manner to keep potential pollutants from coming into contact with stormwater to eliminate or avoid exposure. When exposure cannot be avoided prevent contaminated stormwater from being transported off-site.

• Contain Materials and Wastes: Store construction, building, and waste materials in designated areas that are protected from rainfall and contact with stormwater runoff.

Dispose of construction waste in designated areas, and keep stormwater from flowing onto or off of these areas. Prevent spills and clean up spilled materials.

Identify BMP Categories

Once the BMP objectives are defined, identify the category of BMP best suited to meet each objective. The BMPs selected from each category depend on specific site conditions, construction activities, and cost considerations. There are six BMP categories:

• Erosion Control (EC)

• Sediment Control (SE)

• Wind Erosion Control (WE)

• Tracking Control (TC)

• Non-Stormwater Management (NS)

• Waste Management and Materials Pollution Control (WM)

Select BMPs

BMPs for erosion and sediment control are listed in the EC, SE, WE, and TC categories. BMPs for contractor activities are listed in the NS, and WM categories. This is a general division of the

BMP categories but there will some overlap especially as some contractor activities deal with erosion and sediment control BMPs.

BMPs for Erosion and Sediment Control

BMPs for erosion and sediment control are selected to meet the BMP objectives based on specific site conditions, construction activities, and cost. Various BMPs may be needed at different times during construction since activities are constantly changing. Erosion control BMPs are a source control practice that protects the soil surface and prevents soil particles from being detached by rainfall, flowing water, or wind. Sediment control BMPs are treatment control practices that trap soil particles after they have been detached and moved by rain, flowing water, or wind. Selection of erosion control BMPs should be based on minimizing disturbed areas, stabilizing disturbed areas, and protecting slopes and channels. Selection of sediment control BMPs should be based on retaining sediment on site and controlling the site perimeter.

BMPs for Contractor Activities

Certain contractor activities may cause pollution if not properly managed. BMPs should be selected based on the contractor activities information collected in the assessment of planned activities. The BMP objectives for contractor activities are practicing good housekeeping and containing materials and waste. BMPs for contractor activities are selected from the NS and WM categories, which are presented in Section 4. Several considerations for selecting a BMP for contractor activities include:

• Is it expected to rain? Selection of a BMP is different for the rainy season versus the dry season. Consider rescheduling activities for less rainy periods if possible.

• Will water be used and how much? The more water used and wastewater generated, the more likely that pollutants will be transported by this water. BMPs will be needed to contain or treat water that contacts potential pollutants to prevent them from being transported off-site.

• What are the site conditions? BMPs will differ depending on whether the activity is conducted on a slope or on flat ground and whether the activity is near a drainage structure or watercourse.

• What about accidents? Controls for common activities should be established, and preparations should be made to allow for quick response to accidents or spills including contingency plans for clean up and for sampling the contaminated stormwater.

BMP Maintenance

BMP inspections and visual site monitoring provide the information to determine needed maintenance and the general condition of the installed BMP systems. All maintenance related to a storm event must be initiated within 72 hours of the inspection, and should be completed as soon as possible but preferably before the next predicted storm event. The following maintenance tasks should be performed on a regular basis:

• Removal of sediment from barriers and sedimentation devices;

• Replacement or repair of worn or damaged silt fence fabrics or fiber rolls;

• Replacement or repair of damaged structural controls;

• Repair of damaged soil stabilization measures; and

• Other control maintenance as defined in each BMP fact sheet.

All inactive soil disturbed areas on the project site, and most active areas prior to the onset of rain, must be protected from erosion. Soil disturbed areas may include relatively flat areas as well as slopes. Typically, steep slopes and large exposed areas require the most robust erosion controls;

flatter slopes and smaller areas still require protection, but less costly materials may be appropriate for these areas, allowing savings to be directed to the more robust BMPs for steep slopes and large exposed areas. Additional guidance on the selection of temporary slope stabilization methods is provided in Appendix F. To be effective, erosion control BMPs for slopes at disturbed areas must be protected from concentrated flows. Some erosion control BMPs can be used effectively to temporarily prevent erosion by concentrated flows. These BMPs, used alone or in combination, prevent erosion by intercepting, diverting, conveying, and discharging concentrated flows in a manner that prevents soil detachment and transport. Temporary concentrated flow conveyance controls may be required to direct run-on around or through the project in a non-erodible fashion.

Sediment Control

Sediment control is any practice that traps soil particles after they have been detached and moved by rain, flowing water, or wind. Sediment control measures are usually passive systems that rely on filtering or settling the particles out of the water or wind that is transporting them. Sediment control BMPs include those practices that intercept and slow or detain the flow of stormwater to allow sediment to settle and be trapped. Sediment control practices can consist of installing linear sediment barriers (such as silt fences, gravel bag berms, or fiber rolls); and constructing check dams, a sediment trap or sediment basin to retain sediment on site. Linear sediment barriers are typically placed below the toe of exposed and erodible slopes, down-slope of exposed soil areas, around soil stockpiles, and at other appropriate locations along the site perimeter. Some BMPs are dual-purpose, such as Fiber Rolls and Check Dams. By reducing effective slope length or steepness, these BMPs reduce erosion as well as promote sedimentation. Sediment control BMPs are most effective when used in conjunction with erosion control BMPs. The combination of erosion control and sediment control is the most effective means to prevent sediment from leaving the project site and potentially entering storm drains or receiving waters. The General Permit requires that sediment controls be established and maintained at all sites and requires the combined use with erosion controls to protect disturbed areas at most sites.

Wind Erosion Control

Wind erosion control consists of applying water or other dust palliatives to prevent or minimize dust nuisance.

6.0 INSTALLATION SUPPLEMENT- STORMWATER CONTROL MEASURES

The following information provides stormwater control measures for each BMP.

Minimize Exposure BMPs

Minimize exposure control measures are applicable to all industrial areas on the Base. Numerous

DoD policies and procedures dictate material management practices that are rigorously enforced at all levels of management. Generally, minimize exposure practices involve maintaining orderly work areas, minimizing use of chemicals, and controlling exposure of pollutant sources to stormwater. The following minimize exposure measures are implemented at the Base.

Control Measure Minimize Exposure General

Description The Base must take actions to minimize the exposure of potential sources of pollutants (including loading and unloading, storage, disposal, cleaning, maintenance, and fueling operations) to rain, snow, snowmelt, and runoff.

When possible, the Base will either locate these industrial materials and activities inside or protect them with storm-resistant coverings.

Description Standard industry practice is for drums to be placed on elevated surfaces (e.g., PVC footings, pallets, storage racks, or other suitable materials), thereby keeping the drums out of containment water and reducing the potential for corrosion by preventing moisture contact with drum bottoms. Drums will be covered to prevent standing water from accumulating on the tops of the drums. Used tires that are stored outside should be on a raised surface and covered to protect them from coming into contact with stormwater.

Responsible Individual(s) Facility Personnel

Good Housekeeping BMPs

Good housekeeping measures are applicable to all industrial areas on the Base. Numerous DoD policies and procedures dictate good housekeeping practices that are rigorously enforced at all levels of management. Generally, good housekeeping practices involve maintaining orderly work areas, minimizing use of chemicals and controlling exposure of pollutant sources to stormwater.

The following good housekeeping measures are implemented at Travis AFB.

Control Measure General Maintenance and Work Area Cleanliness

Used spill kit components will be containerized, transported, and disposed of properly. Spent components should be replaced as documented in the ICP. If a large release occurs, procedures are in place, and implemented under the Base IPC, to respond to the specific components of the spill, including remediation and reporting procedures. Spill kit sizes and supplies vary depending on need.

Responsible Individual(s) Facility Personnel

Associated Activities All industrial Activities where liquids are used

Control Measure Drip Pans

Description Temporary drip pans (6 inches deep) will be used to catch drips. Drip pans will be used under valves, pipes, hoses, and drains, etc., pending maintenance, so that the materials or chemicals can be easily cleaned up or recycled before they can contaminate stormwater. Drip pans will be used as a preventive measure. Although drip pans are useful as temporary solutions for containing leaks, the necessary repairs must be performed as soon as possible.

Responsible Individual(s) Facility Personnel

Control Measure Facility Security

Description The Base is a secured facility (i.e., fenced perimeter with guards posted at all entrances and exits). These measures effectively prevent unauthorized access to the facility. Most hazardous waste satellite and accumulation points are located in locked sheds or controlled work areas. Access to materials located in areas of concern is restricted to authorized personnel by using signs, lockable doors/containers, and/or locked gates. Waste drum storage containers or sheds will be locked to prevent access by personnel without the proper authorization. By limiting access to materials, the chance for spills, mixing of materials or chemicals, and improper handling can be reduced.

Responsible Individual(s) Facility Personnel

Control Measure Labeling of Containers

Description Drums and tanks will be clearly labeled. Labels on tanks and drums should indicate material type and container contents.

Two effective labeling methods include color-coding and

Department of Transportation labeling. Accurate labeling can help personnel to quickly identify the type of material so that, in the event of a release, personnel can respond accordingly.

Hazardous material and hazardous waste requirements are found under the associated management plans.

Control Measure Material Inventory Tracking

Description The Base uses the U.S. Air Force Enterprise Environmental, Safety, and Occupational Health Management Information

System

(EESOH-MIS), a comprehensive web-based automated information system for the aggregation and collection of environmental, safety, and occupational health data, which is used to maintain an annual listing of materials used at each building. Tracking materials helps maintain control over the type and quantity used, and reduces excessive amounts of materials stored on site, thus reducing the risk of spills.

Maintaining a material inventory also provides data that are useful in efforts to eliminate or minimize chemical usage.

Responsible Individual(s) Facility Personnel

Control Measure Proper Disposal of Accumulated Stormwater from

Secondary Containment

Description Stormwater that accumulates in secondary containment structures is visually examined prior to discharge to ensure that no contamination is present. The sampling team will observe and record the presence or absence of a sheen or odor. If observed in the water collected in the secondary containment structure, then the contaminant is removed before the water is discharged to the stormwater system. All observations and discharges from secondary containment will be logged to include the date, approximate time, locations observed, presence and probable source of observed pollutants, name of person(s) that conducted the observations, and any response actions and/or additional BMP template revisions necessary in response to the visual observations.

Responsible Individual(s) Facility Personnel

Maintenance BMPs

Maintenance control measures include activities to inspect, maintain, and/or repair equipment, including structural BMPs and the storm drainage system, to prevent or reduce pollution in the

Base stormwater discharges. The Water Quality Program Manager serves as the Maintenance coordinator for the Base stormwater system. Vehicle, equipment, and secondary containment structures/devices (such as curbs and spill pallets) are regularly inspected by facility personnel to identify any items that require maintenance or replacement to prevent releases to storm drains.

Aboveground and underground storage tanks at Travis AFB are regularly inspected by the designated tank custodians.

Control Measure General Preventive Maintenance Program

Description The Base’s preventive maintenance program includes:

• Annual inspection and maintenance of stormwater management devices (e.g., catch basins, culverts, inlets) as required.

• Identification and inspection of all equipment and systems used outdoors that may spill or leak pollutants, in accordance with existing Air Force inspection procedures contained in technical orders and other environmental plans.

• Monthly visual inspections of industrial areas conducted by facility personnel, and initiation of maintenance/repair actions if required.

• Proper maintenance of facility equipment and systems, including identification of equipment that needs to be inspected, scheduled periodic inspections, timely adjustment, and maintenance of complete records.

“Equipment and systems” include any vehicle, machinery, storage tank, or monitoring device, the operation of which creates a potential for stormwater contamination.

• Enhanced training to reduce fuel-handling spills attributable to human error.

Responsible Individual(s) Facility Personnel

Control Measure Tank Inspections and Maintenance

Description Inspections of tanks and ancillary structures (e.g., transfer pipes, secondary containment, etc.) will be conducted according to the tank inspection program described in the

Base ICP. All permanent tanks in contact with the ground (underground storage tanks and direct-contact aboveground storage tanks) will be cathodically protected to reduce the potential for corrosion. The general factors considered during visual tank inspections include:

• Internal corrosion;

• External corrosion;

• Condition of welded joints;

• Tank distortions;

• Tank settlement;

• Visible flaws and visible leaks;

Tanks will be integrity tested IAW the ICP.

Control Measure Periodic Visual Inspections of Equipment and

Infrastructure

Description • Periodic visual inspections will be conducted on all equipment and containers to ensure there are no signs of leakage or corrosion. Piping, pumps, storage tanks, pressure vessels, and process- and materials-handling equipment will be inspected for leaks, signs of corrosion, support or foundation failure, or other deterioration or non-containment.

• Routine inspections of stormwater management devices are performed annually. Some inspections are performed more frequently, as needed.

• Catch basins will be cleaned when the depth of debris reaches two-thirds of the sump depth; and the debris surface will be kept at least six inches below the lowest outlet pipe when feasible, based on design and construction of the catch basin. Some catch basins on

Base are not equipped with sumps and the outlet pipe is located at the bottom of the catch basin. In these situations, cleaning will be accomplished to minimize pollutant discharges and ensure system functionality.

• Visual evaluations of equipment listed in the ICP are performed at periods dictated by the schedule in the ICP.

Control Measure Government Vehicle Inspection and Maintenance

Description Government vehicles are inspected prior to use as required by Air Force and Army policy. Appropriate maintenance/repair actions are initiated for any deficiencies identified during the inspection, as identified by the maintenance schedule. Vehicle checks and repairs are documented.

Spill Prevention and Response

The Base has developed and implemented the IGP that details emergency response operations for the Base, including spill prevention and response procedures. Additionally, Travis AFB has also developed an ICP in accordance with 40 CFR part 112. The IGP provides detailed step-by-step descriptions for first responders to spills as well as training requirements for facility personnel and contractors who manage or handle hazardous materials and petroleum products. In addition, the

ICP describes all necessary and appropriate oil spill response equipment and its locations, and spill response equipment maintenance procedures. The ICP also includes inspection requirements for oil storage and handling areas, and requirements to report and address problems identified during inspections. The ICP provides specifications for training of personnel and contractors who handle hazardous materials and petroleum products in spill prevention and first response activities for spills and hazardous material emergencies.

Control Measure General Spill Prevention and Response

Description ASTs and USTs, containers, and piping are routinely inspected under the Base ICP. Spills are quickly responded to and tracked under this same program. The Base maintains all operational equipment, vehicles, and aircraft using their mechanics and maintenance shops. All personnel are trained as necessary on how to report and respond to leaks, mechanical failures, and accidental spills.

In the event of a spill of hazardous material or waste, the person discovering the spill is required to follow the reporting procedures outlined in the Base ICP.

The qualified responder may initiate spill response actions, including:

• Securing the spill site to prevent unauthorized entry;

• Containing the spill if possible; and

• Supporting cleanup efforts as directed by the Incident

Commander. Hazard communication training will be provided to all persons working in an area where potentially hazardous conditions may be found.

SDSs will be kept for each hazardous material used in a shop and will be posted in the work area or easily accessible for reference in the event of a release.

All contractors must have a Spill Prevention and Response

Plan that will adequately address a spill response in the event a contractor incurs a hazardous material spill. The plan will not be less stringent than the Travis AFB ICP.

The Base HWMP provides guidance for the generation, handling, storage, and disposal requirements for all hazardous waste on Base. The most current version of the document can be found at 60 CES/CEIE and is accessible upon request. It is also accessible digitally to DoD employees through the eDASH database.

Description Personnel follow detailed procedures found in AFI 32-1001, Civil Engineer Operations, Chapter 13, Snow and Ice Control

Program; and AF Technical Order 42C-1-2 for anti-icing and deicing and defrosting of parked aircraft. Personnel responsible for snow and ice removal are required to review the specific manuals kept at each shop which familiarize personnel with BMPs for managing deicing applications. The following practices are in place to avoid unnecessary application of aircraft deicing fluid, and to minimize the exposure of deicing fluid to stormwater:

• Dry-weather deicing involves delaying the flight or placing the aircraft in a hangar to thaw unless it is a priority flight.

• Manual removal of snow is performed whenever possible.

• Pilots determine if deicing is necessary. Deicing is normally performed during a freeze, not a frost. When deicing is deemed necessary, personnel applying the deicing chemical, propylene glycol (PG), determine the percentage of PG to be used based on a temperature-versus-PG table. The range is 10–50 percent.

• If aircraft are grouped close together, deicing is delayed, to prevent high concentrations of deicing fluid runoff.

• A deicing log is maintained providing the date, time, quantity of fluid, and location of the deicing event; and

• Purging is not authorized or allowed.

• The lines are drained and de-icing fluid is disposed.

Control Measure Aircraft, Vehicle and Equipment Washing

Description The following practices are in place to minimize the exposure of cleaning agents, dirt, and grease to stormwater and are documented in the SOPs:

A non-phosphate-based, biodegradable cleaning detergent is used for washing detergent. Non-toxic or low-toxicity detergents, solvents, and degreasers are used in most places (i.e., non-caustic detergents, non-chlorinated solvents) for degreasing solvents.

• All aircraft, vehicle, and equipment washing will be conducted at designated wash racks that drain to the sanitary sewer system.

• Most military aircraft washing activities are conducted inside, but some are conducted outside at a ramp area in conformance with the SOP. Museum heritage aircraft follow their own SOP for washing activities.

• Allow fund-raising privately-owned vehicle (POV) car-washes only in a designated area that drains to a grassy, permeable area for infiltration Vehicle and equipment washing are conducted at enclosed wash rack. Wash water is collected by floor drains, conveyed to an OWS, and discharged to the sanitary sewer system.

• If the wash rack is an open facility, the wash pad should be washed off after completion of the washing activity.

Control Measure Pesticide/Herbicide Selection and Application

Description • The following practices are in place to minimize the exposure of pesticides and herbicides to stormwater:

• Only trained and licensed personnel apply pesticides and herbicides.

• No application takes place prior to forecasted rain events.

• On-site runoff areas are visually monitored for residual and migrating pollutants, to identify potential problem sources.

• Grass is cut frequently, to reduce the need for herbicides.

• Application activities are scheduled such that similar chemicals are applied to all designated areas within several days, to make use of excess and residual from previous applications.

• Application is performed at or below the manufacturer's suggested rate.

• Only the necessary amount of herbicides/pesticides is mixed.

• Broadcast application of herbicides has been eliminated;

spot treatment for weeds using portable hand-held units has been substituted.

• Pesticides that are or will be listed as “Toxics of Concern” on the local, state, or federal level are not used on Base.

• Low-volatility carrier liquids are used.

• The use of atrazine has been eliminated.

• Bait or rodenticides are used for building treatment.

• Pre-emergent herbicides that prevent germination and that are typically less toxic are used.

• Use of phenoxy herbicides that are typically used in post-emergent applications has been minimized or eliminated.

• The use of short half-life compounds having the least proven human toxicity is emphasized.

• New chemicals on the market that have not been thoroughly tested for human toxicity are avoided.

• Trained pesticide applicators may periodically apply low-toxicity pesticides to control potentially dangerous tick, flea, and mosquito populations. Applications are based on

Military Public Health risk data.

• Short half-life herbicides are applied in minimal quantities to roadway shoulders.

Erosion and Sediment Controls

Travis AFB has relatively flat topography which allows sediment and erosion to be controlled by structural and vegetative practices. Soils in the developed areas of the installation are protected by pavements, facilities, and landscaping. Stormwater that falls in the developed areas of the installation is conveyed via a storm drainage system to the outfalls described in Section 1.0. Soils in the undeveloped areas of the installation are protected using vegetative stabilization. There are several areas in which riprap has been placed to protect underlying soils particularly in areas of channelized flow.

Control Measure Grounds Maintenance

Description Landscape and vegetative areas in the industrial areas of the installation are susceptible to sedimentation, dust generation, and erosion. These areas are maintained by the ground maintenance contractor. The grounds maintenance contract statement of work includes specifications to repair damaged areas where erosion has occurred or may occur, for replacement and regrading of damaged soil or ground cover materials, and reseeding or replacement of plants, where applicable. The statement of work specifies the requirements for preventive maintenance for vegetated areas, including fertilizer application, soil aeration, and removal and/or replacement of plants and trees. Dust control must be implemented for street sweeping, grounds mowing, or any activity that generates dust.

Control Measure Construction Projects and General Erosion and Sediment

Control

Description Regulated construction activities (construction activities that disturb one or more acres or are part of a larger common plan of development) performed on the Base require permit coverage under the California Construction General Permit

(CGP). If deficiencies in the construction contractor’s stormwater program are identified, requests for corrective actions are sent to the contractor. Any projects or areas that have been identified to require erosion or sediment control will utilize the required basic BMPs: Implement effective wind erosion controls, Provide effective stabilization for inactive areas, finished slopes, and other erodible areas prior to a forecasted storm event, Maintain effective perimeter controls and stabilize all site entrances and exits to sufficiently control discharges of erodible materials from discharging or being tracked off the site, Divert run-on and storm water generated from within the facility away from all erodible materials, and, if sediment basins are implemented, ensure compliance with the design storm standards presented in the IGP section X.H.6. Use fiber rolls to intercept runoff, spread runoff into sheet flow, avoid development of, rivulets, and reduce erosion and trap sediment.

Control Measure Non-Stormwater Discharge - Dewatering

Description There will be no turbid discharges to surface waters of the state resulting from dewatering activities. If trench or groundwater operations contain sediment, the water must pass through a sediment settling pond or other equally effective sediment control device prior to being discharged.

Care must be taken when discharging groundwater to ensure that it does not become pollutant-laden by contact with disturbed soils or other pollutant sources. If the groundwater is in a designated plume area, the groundwater cannot be discharged to the storm drain system. Contact the WQPM.

Discharging into the stormwater system must be authorized by CEIE Natural Resource.

Management of Runoff

The IGP requires a description of stormwater management practices and permanent structural control measures used to meet established effluent limits. Stormwater runoff on the Base is primarily conveyed through a piping and open channel flow network to the outfalls previously discussed.
