PART I Page 8 of 20
Permit No. COR-040000
B. STORMWATER MANAGEMENT PLAN - ACTIVE MINES (cont.) 1
5. Comprehensive Inspection
The SWMP shall identify qualified personnel that shall inspect designated equipment and mine areas at appropriate
intervals specified in the plan, at least twice a year (in the spring and fall). The operator shall keep a record of
such inspections. This record shall be made available to the Division upon request and summarized in the Annual
Report (see Part I.EA of the permit).
6. Consistency with Other Plans
SWMPs may reflect requirements for Spill Prevention Control and Countermeasure (SPCC) plans under section 311
of the CWA, or Best Management Practices (BMPs) Programs otherwise required by a CDPS permit, and may
incorporate any part of such plans into the SWMP by reference. The SWMP may rely upon information developed
for other similar pollution control programs, including the Mined Land Reclamation Plan. Appropriate portions of
these other plans may be incorporated in the SWMP by reference, as long as a complete SWMP can be reproduced
and submitted to the requesting agency within the time frame specified in the request. Those portions of the
referenced documents must be included in the submittal. The SWMP must also be readily available to an on-site
inspector.
C. STORMWATER MANAGEMENT PLAN-INACTIVE MINES
A Stormwater Management Plan (SWMP) shall be developed for each inactive mine covered by this permit. The SWMP
shall be prepared in accordance with good engineering practices. (The plan need not be completed by a registered
engineer.) The plan shall identify potential sources of pollution (including sediment) which may reasonably be expected
to affect the quality of stormwater discharges associated with the inactive mining operation. In addition, the plan shall
describe and ensure the implementation of best management practices (BMPs) which will be used to reduce the pollutants
in stormwater discharges associated with the inactive mining operation and to assure compliance with the terms and
conditions of this permit.
Inactive mining operations must implement the provisions of their SWMP as a condition of this permit. The
Division reserves the right to review the plan, and to require additional measures to prevent and control pollution as
needed.
SWMPs which met criteria contained in the previous version of this permit are acceptable.
The SWMP shall include the following items, at a minimum:
1. Description of Mining Activities
The plan shall provide a narrative description of the mining and associated activities that took place at the site. The
narrative description shall report the approximate dates of operation, the total acreage within the mine site and an
estimate of the number of acres of disturbed area. A general description of the location of the mining site relative
to major transportation routes and communities shall also be provided.
2. Site Map
Each plan shall provide a generalized site map or maps which indicate any of the following which may be
applicable:
- mining/milling site boundaries and access and haul roads;
- areas used for storage of overburden, materials, soils, tailings or wastes;
- areas used for outdoor manufacturing, storage or disposal of materials;
- tailings piles and ponds;
- an estimate of the direction(s) of surface flow;
- existing structural control measures to reduce pollutants in stormwater runoff; and
- springs, streams, wetlands and other surface waters.
