Kim,
All of this information had been submitted at one point to you. I have reattached the documents for your use.
Condition 1A: No trespassing signs and the required signage for the DBMS permit are installed at the site. No additional
signs are to be installed at the site. All signs are significantly smaller than the maximum allowed by the Code.
Condition 1B:The CDOW letter contained only recommendations. There are no requirements which need to be
addressed in the CDOW letter.
Condition 1C: Public Works is in compliance with our own requirements.
Condition 1D: Dust abatement will be accomplished by providing dust suppression on internal haul roads via a County
water truck. Additional measures such as spray bars on the crusher and ceasing crushing operations in high wind
conditions may be used for dust abatement.
Condition 1E: The APEN has been attached to this email
Condition 1F: The CDPHE Stormwater Permit is attached to this email.
Condition 1G: Per the Weld County Code, a grading permit is not required for a mining operation if there are no
permanent structures. There are no permanent structures at this gravel pit so Condition 1G is not applicable.
Condition 1H:A signed plat has previously been submitted.
Please let me know if you have any questions.

Clay,
I have reviewed the Mylar map associated with USR-1716 for the Weld County Pierce North Pit and find no evidence of
any of the Conditions of Approval being met. Please provide said documentation and modify the USR map to so reflect
the Board approved permit.
Similarly, Planning staff finds no evidence that USR-1672 for the Fiscus North Mine has been recorded, and further finds
no evidence of any of the Conditions of Approval being met. Please provide said documentation and modify the USR
map to so reflect the Board of County Commissioners approved permit.
Please submit the requisite documents and maps associated with each land use permit. I have attached the Board of

Other Conditions
Chemicals
The permittee did not specify any chemicals for use in waters that may be discharged. On this basis,no chemicals are approved under
this permit. Prior to use of any applicable chemical,the permittee must submit a request for approval which includes the most current
Material Safety Data Sheet(MSDS)for that chemical. Until approved,use of a chemical in waters that may be discharged could
result in discharge of pollutants not authorized under the permit.
Antidegradation
An antidegradation(AD)analysis may apply in the future if additional parameters are added to this certification. Current limits are
technology-based,thus antidegradation does not apply.
Groundwater Contamination
If groundwater contamination is encountered, then the permittee is to contact the Division and, if appropriate, the owner of the
collection system receiving the discharge. Since the discharge of contaminated groundwater is not covered under this permit, the
permittee shall immediately apply for a groundwater remediation certification, which will include appropriate requirements for
additional discharge monitoring and on-site environmental response capabilities.
Sampling
Sampling shall occur at a point after treatment,or after the implementation of any Best Management Practices(BMPs). If BMPs or
treatment are not implemented,sampling shall occur where the discharge leaves control of the permittee,and prior to entering the
receiving stream. Samples must be representative of what is entering the receiving stream.
nitoring and Reporting
charge Monitoring Reports(DMR)must be submitted quarterly as long as the certification is in effect.The permittee shall
is l
provide the Division with any additional monitoring data on the permitted discharge collected for entities other than the Division.
This will be supplied to the Division within 48 hours of the receipt of the data by the permittee.
This certification to discharge is effective long term. For termination of permit coverage,the permittee must initiate this by sending
a letter to the Division requesting the permit certification be terminated.
Best Management Practices
The permittee shall implement and maintain the Best Management Practices(BMP)for the prevention of erosion and the control of
solid and liquid pollutants due to the discharge. BMPs include various options,such as:modification of the pipe discharge structure to
disperse flows;containment of water by hay bales or other comparable structures;the use of geocloth,filter fabric,or plastic sheeting
for protection of containment structures;rip-rap;and/or any other approved methods.
Stormwater Management Plan
See Part I.C.of the permit for stormwater requirements.
At the time of application,the permittee certified that they had developed and implemented a Stormwater Management Plan(SWMP)
for this facility. The permittee shall amend the SWMP whenever there is a change in design,construction,operation,or maintenance
which has a significant effect on the potential for the discharge of pollutants to the waters of the State,or if the SWMP proves to be
ineffective in achieving the general objectives of controlling pollutants in stormwater discharges associated with mining activity. A
copy of the SWMP must be kept on site and provided to the Division upon request.
The General Permit for Sand and Gravel Mining and Processing Operations(and other nonmetallic minerals except fuel)is attached.
The permittee should review this permit for familiarity with all of the permit requirements. If the permittee has questions related to
is certification that cannot be answered by a review of the permit,the permit writer should be contacted.

bond must provide additional information before the permit can be terminated.
STORMWATER DISCHARGES
As required under the Clean Water Act amendments of 1987. the Environmental Protection Agency(EPA)has established a framework
for regulating municipal and industrial stormwater discharges. The Water Quality Control Division("the Division")has stormwater
regulations(SCCR 1002-61)in place. These regulations require specsfic types of industrial facilities that discharge stormwater
associated with industrial activity(industrial stormwater), to obtain a CDPS permit for such discharge. The regulations specifically
include sand and gravel mining activities as industrial facilities. Facilities which discharge industrial stormwater either directly to
surface waters or indirectly, through municipal separate storm sewers, must be covered by a permit. This general permit does not cover
.stormwater only discharges, which are covered under stormwater permit CUR-340000_
The federal effluent guidelines that govern discharges from sand and gravel mining facilities(40 CFR 436)control most surface runoff
However, there are some sources ofstormwater from these sites which are not addressed,such as roads and railroad lines,pond
outslopes, inactive loadouts, sites used for storage and maintenance of material handling equipment. etc.
1. Stormwater Management Plan(SWMP): The.store nvaler regulations primarily apply to areas not covered by 4U CFR Part
436. They require permittees to develop and implement a Stormwater Management Plan(SWMP)to protect the quality of
stormwater leaving the site. The plan shall identify potential sources of pollution(including sediment)which may reasonably be
expected to affect the quality ofstormwater discharges associated with mining activity. In addition, the plan shall describe the
best management practices(BMPs)which will he used to reduce the pollutants in stormwater discharges from the mining site.
Some activities required under the SWMP may already he in place. However, the SWMP will require the permittee to
coordinate these activities with any necessary new activities in an orderly manner,so that the result is the reduction or
elimination of pollutants reaching state waters front areas not limited by effluent limitations. Facilities must implement the
provisions of the SWMP required under this part as a condition of this permit.
0 It is the permittee'x responsibility to notify the Colorado Division of Reclamation, Mining and Safely of any significant changes
at their site resulting from the implementation of the SWMP. This is so that the Division of Reclamation. Mining and Safety may
review the SWMP and incorporate any potential revisions into the facility's reclamation permit which might he needed
The SWMP shall include the following items, at a minimum:
a) Site Map

2) Materials handling and spill prevention
3) Erosion and sediment controls
4) Other pollution prevention measures
5) Preventive maintenance
6) Good housekeeping
7) Identification of discharges other than Stormwater.
2. Other Requirements
a) Facility Inspections: The permittee will he required to make a thorough inspection of their stormwater management
system, at least twice per year(in the spring and fall). (See Part I.D.4 of the permit for alternate schedules.) These
inspections must be documented and summarized in the Annual Report to the Division.
b) Employee Education: The permittee shall develop and implement employee education programs to inform personnel at
all levels of responsibility of the components and goals of the SWMP. This section has been expanded from the previous
permit to include contractor and temporary personnel, in keeping with other stormwater permits.
E. Stormwater Management Plan(SWMP)
The SWMP Contents section has been modified. Some of the changes are limited to organization of information, which does not
require modification of an existing permittee's current SWMP. Most of the SWMP changes involve clarifications,reformatting, or
adopting requirements from the Division's Stormwater Construction general permit(e.g.. BMP installation specifications). For
existing permiltees(le., those with permit coverage prior to the reissuance date of this permit), their SMWP must be amended to
include the new required items:
For existing permittees, any SWMP changes based on the change in permit requirements must be completed within 5 months of the
•
effective date of the certification. The plan is not to be submitted to the Division unless requested, but must be available on site as
outlined in Part I.D.S(b)of the permit.
I, Terms and Conditions,General Limitations and Design Standards: This section reiterates the requirement that facilities select, install, implement, and maintain appropriate BMPs,following good engineering, hydrologic and pollution control
practices. In addition, requirements to adequately design BMPs to prevent pollution or degradation of State waters(see Part
I.D?of the permit)have been revised and are discussed below.
?. Site Map: The list of items needed for the Site Map has been expanded in order to adequately characterize the site. A list of
items and factors has been added to the section on identifying potential stormwater pollutants, in order to dares the
Division's intent in this area This requirement may necessitate changes to existing permittees'SWMPs.
3. Description of Potential Pollutant Sources: The requirement to identify Potential Pollutant Sources has been expanded to
include inure details for the evaluation of such sources. This evaluation allows for the appropriate selection of BMPs for
implementation at a facility or site. This requirement may necessitate changes to existing permittees'SWMPs.
-! Stormwater Management Controls: See Part I.C.I of the permit.
a) This section has been modified to require identification of a SWMP Administrator. The SWMP Administrator is a specific
individual(s),position or title who is responsible for the process of developing. implementing, maintaining, and revising
the.S13MP This individual serves as the comprehensive point of contact for all aspects of the facility's SWMP. This
requirement may necessitate changes to existing permittees'SWMPs.
b) Sections have been added requiring that preventive maintenance and good housekeeping measures be included in the
• SWMP. Preventive maintenance is critical to ensuring the success of the B1'LPs at a site. Good housekeeping measures
are a common sense means of increasing compliance. This requirement► ap necessitate changes to existing permittees'
SWMPs.
Permit Termination: .4 section has been added on additional SWMP items for sites seeking permit termination, This section
provides more guidance to permitees than has been available in the past, on the steps needed to inactivate a site's permit

coverage. Most.sites will he able to inactivate coverage once they have had bond release from the Colorado Division of
Reclamation, Mining and Safety. This requirement may necessitate changes to existing permiltees'SWMPs.
III6. Consistency with Other Plans: A section has been added claming that other documents,such as an SPCC, can be used to
meet some of the SWMP requirements,provided that the other documents are readily available and the SMWP includes
appropriate cross references.
