  What is the NPDES stormwater permitting program for industrial
  activity?
  Activities, such as material handling and storage, equipment maintenance and cleaning, industrial
  processing or other operations that occur at industrial facilities are often exposed to stormwater. The
  runoff from these areas may discharge pollutants directly into nearby waterbodies or indirectly via
  storm sewer systems, thereby degrading water quality.

  In 1990, the U.S. Environmental Protection Agency (EPA) developed permitting regulations under the
  National Pollutant Discharge Elimination System (NPDES) to control stormwater discharges associated
  with eleven categories of industrial activity. As a result, NPDES permitting authorities, which may be
  either EPA or a state environmental agency,  issue stormwater permits to control runoff from these
  industrial facilities.

  What types of industrial facilities are required to obtain permit
  coverage?
  This fact sheet discusses stormwater discharges from asphalt paving and roofing materials
  manufacturers and lubricant manufacturers as described by Standard Industrial Classification (SIC)
  Major Group 29. Only facilities that perform the following operations require coverage under an
  industrial stormwater permit:
    4 Asphalt paving mixtures and blocks (SIC 2951)
    4 Asphalt felts and coatings (SIC 2952)
    4 Lubricating oils and lubricating oils and greases (SIC 2992)
    4 Products of petroleum and coal not elsewhere classified (SIC 2999)

  Not discussed in this fact sheet are Tenderers of fats and oils (see Fact Sheet U (EPA-833-F-06-036)
  for food and kindred products), oil recycling facilities (see Fact Sheet N (EPA-833-F-06-029) for scrap
  recycling facilities), or petroleum refining facilities.

  What does an  industrial stormwater permit require?
  Common requirements for coverage under an industrial stormwater permit include development of
  a written stormwater pollution prevention plan (SWPPP), implementation of control measures, and
  submittal of a request for permit coverage, usually referred to as the Notice of Intent or NOI. The
  SWPPP is a written assessment of potential sources of pollutants in stormwater runoff and control
  measures that will be implemented at your facility to minimize the discharge of these pollutants
  in runoff from the site. These control measures include site-specific best management practices
  (BMPs), maintenance plans, inspections, employee training, and reporting. The procedures detailed
  in the SWPPP must be implemented by the facility and updated as necessary, with a copy of the
  SWPPP kept on-site. The industrial stormwater permit also requires collection of visual, analytical,
  and/or compliance monitoring data to determine the effectiveness of implemented BMPs. For more
  information on EPA's industrial stormwater permit and links to State stormwater permits, go to

  What pollutants are associated with activities at my facility?
  Pollutants conveyed in stormwater discharges from facilities involved with the manufacturing of
  asphalt, roofing materials, and lubricants will vary. There are a number of factors that influence to
  what extent industrial activities and significant materials can affect water quality.
     4 Geographic location
     4 Topography
     4 Hydrogeology
     4 Extent of impervious surfaces (e.g., concrete or asphalt)
     4 Type of ground cover (e.g., vegetation, crushed stone, or dirt)
     4 Outdoor activities (e.g., material storage, loading/unloading, vehicle maintenance)
     4 Size of the operation
     4 Type, duration, and intensity of precipitation events

  What BMPs can be used to minimize contact between stormwater
  and potential pollutants at my facility?
  A variety of BMP options may be applicable to eliminate or minimize the presence of pollutants
  in stormwater discharges from asphalt paving and roofing materials manufacturers and lubricant
  manufacturing facilities. You will likely need to implement a combination or suite of BMPs to address
  stormwater runoff at your facility. Your first consideration should be for pollution prevention BMPs,
  EPA-833-F-06-019

  which are designed to prevent or minimize pollutants from entering stormwater runoff and/or reduce
  the volume of stormwater requiring management. Prevention BMPs can include regular cleanup,
  collection and containment of debris in storage areas, and other housekeeping practices,  spill control,
  and employee training. It may also be necessary to implement treatment BMPs, which are engineered
  structures intended to treat stormwater runoff and/or mitigate the effects of increased stormwater
  runoff peak rate, volume, and velocity. Treatment BMPs are generally more expensive to install and
  maintain and include oil-water separators, wet ponds, and proprietary filter devices.

  BMPs must be selected and implemented to address the following:

  Good Housekeeping Practices
  Good housekeeping is a practical, cost-effective way to maintain a clean and orderly facility to prevent
  potential pollution sources from coming into contact with stormwater. It includes establishing proto-
  cols to reduce the possibility of mishandling materials or equipment and training employees in good
  housekeeping techniques. Common areas where good housekeeping practices should be followed in-
  clude trash containers and adjacent areas, material storage areas, vehicle and equipment maintenance
  areas, and loading docks. Good housekeeping practices  must include a schedule for regular pickup and
  disposal of garbage and waste materials and routine inspections of drums, tanks, and containers for
  leaks and structural conditions. Practices also include containing and covering garbage, waste materi-
  als, and debris. Involving employees in routine monitoring of housekeeping practices has  proven to
  be an effective means of ensuring the continued implementation of these measures.

  Minimizing Exposure
  Where feasible, minimizing exposure of potential pollutant sources to precipitation is an  important
  control option. Minimizing exposure prevents pollutants, including debris, from coming into contact
  with precipitation and can reduce the need for BMPs to treat contaminated stormwater runoff. It can
  also prevent debris from being picked up by stormwater and carried into drains and surface waters.
  Examples of BMPs for exposure minimization include covering materials or activities with  temporary
  structures (e.g., tarps) when wet weather is expected or moving materials or activities to existing
  or new permanent structures (e.g., buildings, silos, sheds). Even the simple practice of keeping a
  dumpster lid  closed can be a very effective pollution prevention measure.

  Erosion and Sediment Control
  BMPs must be selected and implemented to limit erosion  on areas of your site that, due to
  topography, activities, soils, cover, materials, or other factors are likely to experience erosion. Erosion
  control BMPs such as seeding, mulching, and sodding prevent soil from becoming dislodged and
  should be considered first. Sediment control BMPs such  as silt fences, sediment ponds, and stabilized
  entrances trap sediment after it has eroded. Sediment control  BMPs should be used to back-up
  erosion control BMPs.

  Management of Runoff
  Your SWPPP must contain a narrative evaluation of the  appropriateness of stormwater management
  practices that divert,  infiltrate, reuse, or otherwise manage stormwater runoff so as to reduce the
  discharge of pollutants. Appropriate measures are highly site-specific, but may include, among others,
  vegetative swales, collection and  reuse of stormwater, inlet controls, snow management,  infiltration
  devices, and wet retention measures.

  A combination of preventive  and treatment BMPs will yield the most effective stormwater
  management for minimizing  the offsite discharge of pollutants via stormwater runoff. Though not
  specifically outlined in this fact sheet, BMPs must also address preventive maintenance records or
  logbooks, regular facility inspections, spill prevention and response, and employee training.

  All BMPs require regular maintenance to function as intended. Some management measures have
  simple maintenance requirements, others are quite involved. You must regularly inspect all BMPs to
  ensure they are operating properly, including during runoff events. As soon as a problem  is found,
  action to resolve it should be initiated immediately.
  Implement BMPs, such as those listed below in Table 2 for the control of pollutants at asphalt paving
  and roofing materials manufacturers and lubricant manufacturing facilities, to minimize and prevent
  the discharge of pollutants in stormwater. Identifying weaknesses in current facility practices will aid
  the permittee in determining appropriate BMPs that will achieve a reduction in pollutant loadings.
  BMPs listed in Table 2 are broadly applicable to asphalt paving and roofing materials manufacturers
  and lubricant manufacturing facilities; however, this is not a complete list and you are recommended
  to consult with regulatory agencies or a stormwater engineer/consultant to identify appropriate BMPs
  for your facility.

  What if activities and materials at my facility are not exposed to
  precipitation?
  The industrial stormwater program requires permit coverage for a number of specified types of
  industrial activities. However, when a facility is able to prevent the exposure of ALL relevant activities
  and materials to precipitation, it may be eligible to claim no exposure and qualify for a waiver from
  permit coverage.

  If you are regulated under the industrial permitting program, you must either obtain permit coverage
  or submit a no exposure certification form, if available. Check with your permitting authority for
  additional information as not every permitting authority program provides no exposure exemptions.

  Where do I get more information?
  For additional information on the industrial stormwater program see
  www.epa.gov/npdes/stormwater/msgp.

  A list of names and telephone numbers for each EPA Region or state NPDES permitting authority can
  be found at www.epa.gov/npdes/stormwatercontacts.
