• APPENDIX A -SWMP (cont.
Page 3-A
o) SWMP Admtitistrator -The SWMP shall identify a specjf~c individual or individuals within the mining
organization who is responsible jot developing the SWMP and arsistmg the mine operator to its
implementation, mauuenance, and revision.
The SWMP Administrator becomes the contact for all SWMP-related issues and is the person responsible for its
accuracy, completeness, and implementation. Therefore, the SWMP Administrator should be a person in an authoritative
position. Larger facilities may want to develop a "SWMP team" in order to share the responsibilities and generate
greater awareness and participation.
b) Materials Hand6nn and Spill Prevention -Where materials can impact stormwater runoff, BMPs that reduce
the potential jot cotttmnine¢ion shall be described For exmnple, materials should be stored and handled in
covered areas whenever possible to prevent contact with stormwater; fuels and other chemicals should be
stored within berms or secondary containment devices to prevent leaks and spills from entering stormwater
runojJ.
When selecting BMPs, t). ° most important ones to evaluate first aze those which limit the source of the pollutant. It i;
much more efficient, from both a cost and environmental standpoint, to prevent the pollution in the first place than to
clean up contaminated stormwater. For example, a BMP requiring that any vehicle maintenance that involves fluid
exchange must take place indoors, results in the removal of a pollutant source (i.e., oillhydraulic fluids) from possible
contact with storniwater.
Good housekeeping measures, such as cleaning and maintenance schedules, trash disposal and collection practices,
grounds maintenance, etc., can be included here.
c) Erosion and Sediment ControLt - Describe BMPs that will be used to reduce erosion and prevent sediment
delivery to State woters. These should include strucatral (such as silt fences, sediment ponds, drop structures,
check dams) and non-structural (such as mu[chirtg and revegetadon) methods.
BMPs can describe a wide range of management procedures, schedules of activities, prohibitions or practices and other
management practices. BMPs can include operating procedures, treatment requirements and practices to control plant
site runoff, drainage from raw materials storage, spills or leaks. Nonstructural BMPs are mainly definitions of
operational or managerial techniques. Structural BMPs include physical processes ranging from diversion structues to
oil(water separators to retention ponds.
The BMPs selected are up to the judgment of die individual permittee. However, it is important to note that a fully
implemented SWMP will constitute compliance with Best Available Technology (BAT) and Best Conventional Technology
(BCT), as mandated under the Federal Clean Water Act. This means that, in order to comply with your permit, the
appropriate measures must be taken in keeping with the pollutant(s) involved and the risk potential at the facility.
d) Testine for Non-Stormwater -The Stormwater Quality Controls section oJthe SWMP shall ineGtde
documentation that the discharges have been tested or evaluated jot the presence ojnon-smrntwater discharges
such as mine drainage, spoil springs, sanitary wrote, or process water of any kind. The documentation shall
include a description ojthe results of any test jot the presence ojnon-stormwater discharges, the method used,
the date ojany testing, and the on-rue drainage points that were directly observed during the test.
Except for flows from fire fighting activities, all sources of landscaping irrigaxion return flow or springs
(except spoil springs) that are combined with stormwater discharges associated with industrial activity must be
identijted in the plan.
In other words, only stormwater can be conveyed by the stormwater drainage system. Examples of potential illicit
connections include floor drains and toilets in maintenance buildings, chemical storage buildings, etc. There are several
methods of determining whether or not illicit connections exist. Acceptable procedures include dry weather observations
of outfalls or other appropriate locations, analysis and validation of accurate piping schematics, dye tests, etc.
Note - if illicit connections are discovered, corrective measures must be taken.
