Denver, Colorado 80220
Page 3 of 4
Permit No. COC-850028
IV. FACILITY INFORMATION: (continued)
Any discharges from the facility should consist of surface runoff only.
If discharge of mine water, prep plant water, sanitary water or other non-
surface runoff related water becomes necessary, the Permittee will have to
request that an individual NPDES permit be drafted prior to the occurrence
of such discharge, to replace this general permit.
V. ANTIDEGRADATION:
These are not reviewable waters pursuant Co Section 3.1.8(3)(a) of the
Basic Standards and Methodologies for Surface Water (SGGR 1002-2), based
on a finding of no increased water quality impact.
VI. DISCUSSION:
Applicable effluent limitations and monitoring requirements regarding
active mining outfalls, are addressed .in Part I.B.1(a) and I.B.3.(a)
respectively of the general permit.
• Total dissolved solids monitoring of the discharge shall be performed.
Total phosphorus monitoring shall not be performed. See page 3 of the
general permit for more information.
The Permittee will be required to develop and implement a Storm Water
ManagemenC Plan (SWMP). Although some activities may already be in place,
the SWMP will require the Permittee to coordinate best management
practices so the result is a reduction or elimination of pollutants
reaching state water from areas not Limited by effluent limitations. The
Permittee will be required to submit the SWMP to the Division for review
within six months from the date certification is issued. For specifics of
the Plan and additional requirements, please reference the Part I.B.2 of
the general permit.
The permittee will not be required to perform Whole Effluent Toxicity
(WET) testing pursuant to Section 6.9.7(2)(a)(i)(A) of the Regulations for
the State Discharge Permit System 6.1.0 (5 CCR 1002-2) which exempts
facilities certified under the general permit.
VII. SPECIFIC INFORMATION OF CONCERN TO THE PERMITTEE:
The Permittee is encouraged to read the general rationale for an
understanding of how the general permit was developed and to read the
permit itself to see what requirements exist. Effluent limitations and
monitoring requirements are specified in Part I.B, and special
notification requirements for effluent violations are addressed in Part
II.A.3.
