COLORADO DEPARTMENT OF PUBLIC HEALTHAND ENVIRONMENT, Wafer Quality Control Division
Rntionnte -Page 8, Permit No. CO-0038776 '
b. Stormwater Mana¢ement Plans (SWMPs): The purpose of a SWMP is to identify possible pollutant sources to Stormwater
an to set out est managgement practices that, when implemented, will reduce or eliminate any possible water quality
impacts. A SWMP must be maintained far the West Elk Mine in accordance with good engineerzng practices. (The plan
need not be completed by a registered engineer.) The Division has a guidance document avazlable on preparing a SWMP.
The plan identifies potential sources of pollution (including sediment) which may reasonably be expected to affect the
quality of Stormwater discharges associated with mining or remediation operations. In addition, the plan escribes
practices, which will be used to reduce the pollutants in Stormwater discharges from the mining or remediation operation,
and to assure compliance with the terms and conditions of this permit. Facilities must implement the provisions of their
SWMP as a condition of this permit.
There are separate sections in this permit addressing SWMP requirements for pollutant sources in active and inactive
portions of the West Elk Mine.
SWMP For Active Mining Operations -Contents
a) Description ofmining activities
b) Area subject to effluent /zmitations guidelines
c) Site map
Stormwater management controls
1) SWMP Administrator
Z) Identification ofpatenh'al pollulantsources and BMPs
Preventive maintenance
Good housekeeping
) Sppill pprevention and response procedures
6) h.'mplo ee education
77) Identi~cauon ofdischarges other than Stormwater
e) Comprehensive inspection
ii. SWMP For Inactive Mining Operations -Contents
a) Description ofmining activzties
c) Stormwater management controls -Identification ofpotential pollutant sources and BMPs
1) Stormwater diversion
2 Sediment and erosion prevention
d) omprehensive inspecfiors
e) Addztionalltems
Additional SWMP Requirements apply if the West Elk Mine seeks terminations of the Stormwater portion of this
permit. In the event that the permzttee wishes to remediate an inactive mine site and termirsate yermit coverage,
pnor (o remediation activities, the SWMP must be amended to include the following items, and the permittee must
notify the Division of the change in status:
Documentation ojlandowner permission (if the permittee is not the owner)
action to be pezformed
rsn remediatzors activities
of anyy water scored within mine waste
tr BMPs to be used, final site stabilization, and ultimate land use
SWMP Develo ment Coordination and Format: Some activities required under the SWMP may already be in place.
owever, t e wi regttire t e permittee to coordinate these activities with any necessary new activities in an orderly
. manner, so that the result zs the reduction or elimination of pollutants reaching state waters from areas not limited by
numeric effluent limitations.
It is the permittee's responsibility to notify the Colorado Division of Minerals and Geology (CDMG) ojany changes at their
sire resulting from the implementation of the. SWMP. This notification allows the CDMG to review the 5'WMP and
incorporate any potential revisions, which might be needed into the facility's reclamation permit. It is im ortant to verify
that the sire reclamation permit matches the SWMP. Such information is usually contained in Exhibit G of PIO reclamation
permits.
The SWMP may rely upon information developed for other similar pollution control programs such as the SPCC (Spill
Prevention Control and Countermeasures) plan, Voluntary Cleanup Plan, or the Mined Land Reclamation flan.
Appropriate portions o these other plans may be incorporated in the SWMP by reference, as long as a complete SWMP
can be reproduced and submined to the requesttnR agency within the time frame specked in the request. Those portions of
the referenced documenu must be included in the submzttal. The SWMP must also be readily available to an on-site
inspector. -
c. Coin rehensive Facili Ins ections: The permittee shall make a Thorough inspection of their Stormwater management
system, at east twice per yyear in the sprin~ and fall). These inspections must be documented and summarized in the
Annual Report (see Part ID.2.g of the permit .
d. Annual Re ort: The permittee will be required to submit an Annual Report, covering January 1 through December 31 of
eat year, on the compliance with the SWMP. The Annual Report shall contain, at a mznimum:
i. A report on the facility's overall compliance with the SWMP, includirsg a progress reporC on remediation activities.
ii. A summary of all cmprehenszve Stormwater inspections made.
iii. Results dnd interpretatzon of any Stormwater monztoring performed.
The Annual Report will be due to the Division on or before February 1 S of the following year (see Pan I.D.2.g of the
permit).
All reports required for submittal shall be signed and certifed for accuracy by the permittee. (See Part IE.6. of the
permn.)
