E. REPORTING REQUIREMENTS(cont.)
"I certify under penalty of law that this document and all attachments were prepared under my direction or
supervision in accordance with a system designed to assure that qualified personnel properly gather and
evaluate the information submitted. Based on my inquiry of the person or persons who manage the system,
or those persons directly responsible for gathering the information, the information submitted is, to the best
of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties
for submitting false information, including the possibility of fine and imprisonment for knowing violations."
3. Retention of Records
The permittee shall retain a copy of the SWMP required by this permit for the duration of this permit. The permittee
shall retain copies of all reports required by this permit and records of all data used to compete the application to be
certified under this permit, for a period of at least three years.
4. Other Reporting Procedures
Incidents such as spills or other discharges shall be included in the records. Inspections and maintenance activities
shall be documented and recorded. This does not relieve the permittee of the responsibility of reporting spills as
required under section 25-8-601(2) of the Colorado Water Quality Control Act.
F. TERMINATION OF PERMIT COVERAGE
1. Termination Criteria
a. Reclamation Permit Release: When a site has been reclaimed in accordance with the Colorado Division of
Minerals and Geology ("CDMG") requirements and the site has been released from State reclamation
requirements, the permittee may request stormwater permit termination.
b. Termination in the absence of CDMG Permit: For facilities without CDMG permits, permittees wishing to
terminate stormwater permit coverage through mine-waste remediation must amend their SWMP to include the
items listed in Part I.C.5, above, prior to implementation of the remediation work. In addition, permittees
seeking coverage under the Voluntary Cleanup Act must notify the Division of their intent 30 days before any
remediation activities commence. The notification must include certification language and signature by the
permittee. (See Part I.E.2 of the permit.)
Certification under this permit may be terminated once raw materials, intermediate products, byproducts, finished
products and waste products (including acid generating material exposed by the mining activity) have been
removed or isolated and the site has been stabilized (with little evidence of soil erosion or other runoff problem)
and revegetated. The following criteria must be met for the entire mine site, including any on-site disposal areas:
1) all raw materials, intermediate products, byproducts, finished products and waste products (including acid
generating material exposed by the mining activity)have been removed or permanently isolated from
stormwater; and
2) all soil disturbing activities at the site have been completed; and
3) vegetation has been established with an average cover or density, over the previously disturbed area, of a
minimum of 40 percent vegetative cover or 70 percent of the vegetative cover of a similar undisturbed site,
whichever is higher(vegetative cover or density determinations need not be determined scientifically by
extensive measurement and statistical analyses; simple representative transects are adequate.); or equivalent
permanent physical erosion reduction methods have been employed.
The Division may, after consultation with the permittee and upon good cause being shown, revise the vegetative cover
requirement on a case-by-case basis.
