Permit No.: C00038342
3. Federal Effluent Limitation Guideline -Sediment Control Plan (Outfall 003)
ICIS
Code
Description
Due date
Frequency
The permittee shall submit proof to the division that the Sediment Control Plan (SCP)
December 1,
00308
required under Subpart H (40 CFR Part 434.82) has been approved by the Colorado
2015
Annual
Division of Reclamation, Mining, and Safety, and is implemented at the facility.
4. Practice -based Effluent Limitations (Outfalls 001, 003 and 004)
Practice -based limitations required by this permit include the following:
a. Minimize Exposure
The permittee must minimize (as defined in Appendix B) the exposure of pollutant sources associated with
manufacturing, processing, and material storage areas (including loading and unloading, storage, disposal,
cleaning, maintenance, and fueling operations) to rain, snow, snowmelt, and runoff. Minimizing exposure may
include locating these industrial materials and activities inside or protecting them with storm resistant
coverings.
b. Good Housekeeping
The permittee must keep clean all areas exposed to stormwater runoff, as necessary to minimize potential
sources of pollutants, using such measures as sweeping at regular intervals, keeping materials orderly and
labeled, and storing materials in appropriate containers.
c. Maintenance of Control Measures
The permittee must maintain all control measures (structural and non-structural) used to achieve the effluent
limits required by this permit in effective operating condition. The permittee must conduct maintenance of
control measures in accordance with this permit (see CONTROL MEASURES).
d. Spill Prevention and Response Procedures
The permittee must minimize the potential for leaks, spills and other releases that may be exposed to
stormwater and develop plans for effective response to such potential spills. The permittee must at minimum
implement:
i. Procedures for regularly inspecting, testing, maintaining, and repairing all industrial equipment and
systems to avoid situations that may result in leaks, spills, and other releases of pollutants in
stormwater discharged to receiving waters.
ii. Procedures for plainly labeling containers that could be susceptible to spillage or leakage to encourage
proper handling and facilitate rapid response if spills or leaks occur;
iii. Preventative measures such as barriers between material storage and traffic areas, secondary
containment provisions, or procedures for material storage and handling;
iv. Procedures for expeditiously stopping, containing, and cleaning up leaks, spills, and other releases.
Employees who may cause, detect, or respond to a spill or leak must be trained in these procedures
and have necessary spill response equipment available; and
v. Procedures for notification of appropriate facility personnel, emergency response agencies, and
regulatory agencies. Contact information must be in locations that are readily accessible and available.
e. Erosion and Sediment Controls
The permittee must stabilize exposed areas and contain runoff using structural and/or non-structural control
measures to minimize onsite erosion and sedimentation, and the resulting discharge of pollutants. Among other
actions taken to meet this effluent limit, flow velocity dissipation devices must be placed at discharge
Locations and within outfall channels where necessary to minimize erosion and/or settle out pollutants.
f. Management of Runoff
The permittee must divert, infiltrate, reuse, contain, or treat stormwater runoff, in a manner that minimizes
pollutants in stormwater discharges from the site.
g. Salt Storage Piles or Piles Containing Salt
