C'. EFFLUENT LIMTTATIONS AND CONDTITONS - STORMWATIIt DLSCHARGE
e. All dischargers must comply with the lawful regetiremeota of counties, drairuge districts and other state or
local agmci~s regarding any discharges of etormwater to storm drain systems or other water courses under
their jurisdiction.
2. Stormwata Mana¢emmt Plan fSWMPI
A Stormwater Management Plan (SWMP) shall be developed for each facility covered by this section (Part I. C). The
SWMP shall be prepared in accordance with good engineering practices. (The plan need not be completed by a
registered engineer.)
The plea shall identify potential sources of pollution (including sediment) which may reasonably be expected to affect
the quality of stormwater discharges associated with the mining activity. In addition, the plan shall describe end
ensure the implementation of best management prat[ices (BMPs) which will be used to reduce the poflumnta in
stormwater discharges associated with mining activity.
Mining operations must txrtify the tbmpletion of their SWMP and must impl®mt the provisions of the
SWMP required under this part as a mnditioo of this pewit. The Division reserves the right to request and
review the pleoe, a~ad to require additional measures to prevent and control pollution, ae needed.
The SWMP shall include the following items, at a minimum:
a. Site Map
The plea shall provide • site map or maps which indicate at a minimum:
- Mining site boundaries
- Accaa and haul roads
- Stormwater outfalls and an outline of the drainage area of each stormwater outfafl
- An P,~,.,~ea of the direction of flow
- Mateeials handling areas
- Each existing atruclural control measure to reduce pollutants in stormwater runoff
- Areas used for storage or disposal of overburden, materials, soils or wastes
- Areas: used for mineral milling and processing
- Springs, streams, wetlands and other surface waters
- I-ovation of mine dreimge or any other process water
- Boundary of tributary area that ie subject to affluent limitations
- Date the map was prepared
b. Description of Potential Pollutant SotnYes/Mateial InvmWry
The plea shall provide ^ description of all potential sources (activities and materials) dhich may reasonably be
expected to ndd pollutmts to etormwater discharges. Such sources may include haul roads, equipment storage
and maintenance areas, fuel storage arras, etc.
In each case where etormwater pollution potential exists, appropriate preventive measures must be taken and
documented.
a Stormwate' Quality Controls
Each mining site covered by this permit shall develop a description of etormwater quality exmtrols appropriate
for that site, and implement such controls. The appropriateness and priorities of controls in the plm shall
reflect identified potential sources of pollutmte at the site. The description of stormwater quality controls shall
address the following minimum components, including a schedule for implementing such controls:
