Staff comments made during this phase of the application process may not be all-inclusive, as other issues may arise during the remaining application process. COMMENTS: General Project Information/Location: An existing gravel pit is being expanded This project is east of and adjacent to CR 127 and is south of CR 124. Parcel number 021934000009. Access is from CR 127. Roads: County Road 127 is a gravel road and is designated on the Weld County Road Classification Plan as a collector road, which requires 80 feet of right-of-way at full buildout. The applicant shall delineate on the site map the future and existing right-of-way. If the existing right of way cannot be verified it shall be dedicated. All setbacks shall be measured from the edge of future right-of-way. This road is maintained by Weld County. The County Road 124 Section Line is estimated to have 60 feet of unmaintained County line right-of-way. The applicant shall delineate the existing right-of-way and the documents creating the right-of-way and this information shall be noted on the plat. All setbacks shall be measured from the edge of right-of-way. Traffic: Latest ADT on 127 was taken on 12/10/2014 which counted 125 vpd with 55% trucks. A traffic narrative was submitted and indicated that during peak times there will be approximately 25 truck daily roundtrips and 2 employee's round trips/day. The expected traffic routes are 50% heading north and 50% heading south from the access location. Access: An access permit has been approved for the access to the site (AP15-00086). Entrance gates (if applicable) must be set back a minimum of 100 feet from edge of shoulder to allow a truck with trailer or RV to pull completely off of the roadway and open the gate. In no case shall any vehicle(s) stopped to open a gate be allowed to create a safety issue for roadway users. The applicant has shown this on the site plan. Tracking Control: Tracking control is required to prevent tracking from the site onto public roadways. Minimal standards are listed below. Temporary Tracking Control shall be used during construction unless permanent tracking control is installed ahead of construction activities. More than 10 round large truck trips/day or more than 50 round passenger vehicles trips/day: P Access onto gravel roads requires a tracking control device and a minimum of 300ft of recycled asphalt or road base which has been shown on the site plan. *Recycled concrete is not allowed in County ROW **Tracking control devices can be double cattle guards or other specialized device *** Tracking control for unmaintained public ROW is required just prior to entering publically maintained roadways. ****Surface improvements less than 300 ft may be allowed if site constraints would prohibit meeting condition.

(Planning-Engineering) MEMORANDUM ETO: Chris Gathman, Planning Services UL t p U N?T' j FROM: Lauren Light, Environmental Health SUBJECT: USR15-0031 Harms DATE: 8/17/2015 Environmental Health Services has reviewed this proposal for a Site Specific Development Plan and Use by Special Review Permit for a mineral resource development including open pit mining and materials processing (gravel mining operation) in the A (Agricultural) Zone District. As this is a temporary use, portable toilets and bottled water are acceptable for sanitary uses. Noise will be restricted to the level allowed in the industrial zone district. Dust abatement will consist of utilizing a water truck for roads, reducing speeds and tarping loaded trucks. Waste will be removed nightly by personnel on site. The State does not require registration of aboveground fuel storage tanks associated with gravel pits as long as the following requirement is adhered to: "Aboveground storage tanks used to store flammable and combustible liquids at mining facilities and construction and earthmoving projects, including gravel pits, quarries, and borrow pits where, in the opinion of the state inspector of oils, tight control by the owner or contractor and isolation from other structures make it unnecessary to meet the requirements of this article." The fuel tank is double walled and will be contained within a secondary containment berm. We have no objections to the proposal; however, we recommend the following requirements be incorporated into the permit as development standards: 1. All liquid and solid wastes (as defined in the Solid Wastes Disposal Sites and Facilities Act, 30-20-100.5, C.R.S.) shall be stored and removed for final disposal in a manner that protects against surface and groundwater contamination. 2. No permanent disposal of wastes shall be permitted at this site. This is not meant to include those wastes specifically excluded from the definition of a solid waste in the Solid Wastes Disposal Sites and Facilities Act, 30-20-100.5, C.R.S. 3. Waste materials shall be handled, stored, and disposed in a manner that controls fugitive dust, fugitive particulate emissions, blowing debris, and other potential nuisance conditions. The facility shall operate in accordance with Chapter 14, Article 1 of the Weld County Code. 4. The facility shall comply with the Air Pollution Emission Notice (A.P.E.N.) permit requirements as stipulated by the Air Pollution Control Division, Colorado Department of Public Health and Environment, as applicable. 5. Fugitive dust should attempt to be confined on the property. Uses on the property should comply with the Colorado Air Quality Commission's air quality regulations. 6. This facility shall adhere to the maximum permissible noise levels allowed in the Industrial Zone as delineated in Section 14-9-30 of the Weld County Code. 7.

CO 80203 June 22, 2015 Chris Gathman, Planner Weld County Department of Planning Services Transmission via email: cgathman@co.weld.co.us Re: Harms Pit, Case No. USR15-0031 Section 34, T11N, R58W, 6th P.M. Water Division 1, Water District 64 Dear Mr. Gathman: We have reviewed the above referenced proposal for a site-specific development plan and use by special review for a mineral resource development facility on 32.2 acres. The submitted material does not appear to qualify as a "subdivision" as defined in C.R.S. § 30-28-101(10)(a). Therefore, pursuant to the State Engineer's March 4, 2005 memorandum to county planning directors, this office will only perform a cursory review of the referral information and provide comments. The comments will not address the adequacy of the water supply plan for this property or the ability of the water supply plan to satisfy any County regulations or requirements. The proposal is for a gravel mining operation, known as the Harms Pit, which will be operated under Colorado Division of Reclamation Mining and Safety (DRMS) permit no. M-2013-018. The primary commodities to be mined at the site are sand, gravel, rock, and dirt. The site is proposed to be reclaimed to grazing/rangeland upon completion of the mining operation. Comments regarding the reclamation permit conversion were provided to the DRMS in a memo dated December 2, 2014. No groundwater is anticipated to be encountered at the Harms Pit; therefore exposure of ground water must not occur during or after mining operations. The site is anticipated to have four employees on site, with additional visits by material haul truck drivers and other site users. Bottled drinking water will be provided for employees and visitors, and portable toilets will be located on site. Water for dust control purposes is proposed to be pumped from the well with permit no. 69175-F. Industrial use of up to 300 acre-feet per year of ground water is allowed under permit no. 69175-F, subject to all other permit conditions of approval. Any storm water runoff intercepted by this operation that is not diverted or captured in priority must infiltrate into the ground or be released to the stream system within 72 hours; otherwise a substitute water supply plan or augmentation plan approved by water court must be obtained. Please contact Sarah Brucker of this office if you or the applicant have any questions. Sincerely, j ' Tracy L. Kosloff, P.E.
