APPENDIX C (cont.)
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.
INACTIVE MINES
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 Mau
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.
3. Stormwater Management Controls - Identification of Sources and Best Management Practices
The SWMP shall identify potential sources of pollutants at the site and assess the potential of these
sources to contribute pollutants to stormwater discharges associated with mining activities. The
SWMP must also describe appropriate Best Management practices (BMPs) to reduce the potential of
these sources to contribute pollutants to stormwater discharges. The appropriateness and priorities of
controls in the plan shall reflect identified potential sources of pollutants at the mining site. The
description of the BMPs shall include:
a. Stormwater diversion: Describe how and where stormwater will be diverted away from potential
pollutant sources to prevent stormwater contamination.
b. Sediment and erosion prevention: Describe practices that will be used to reduce erosion and
prevent sediment delivery to State waters. These could include structural (such as silt fences,
sediment ponds, drop structures, check dams) and non-structural (such as mulching and
revegetation) methods.
4. Comprehensive Inspection and Record Keeping Procedures
The SWMP shall identify qualified personnel that shall inspect designated areas. Inspections required
by this part shall be conducted annually. Where annual inspections are impracticable, certification
once every three years by a Registered Professional Engineer that the site is in compliance with the
SWMP, is required. The SWMP shall also identify procedures for recordkeeping and internal
reporting.
