equipment and parking and driving areas will use approximately one acre, plus additional
<br />stockpile areas. Water as required for dust control and other air pollution controls (such as
<br />scrubbers, if baghouses are not used) will be transported to the site by truck.
<br />Fuel and AC oil are petroleum products, together with lime and soap and other
<br />potentially water - priority and hazardous materials will be transported and stored on -site in
<br />accordance with federal, state, and county regulations and DRMS guidance, to prevent and
<br />control spills and prevent any nuisance to neighbors or future site occupants.
<br />Waste materials generated by the HMA facility will be recycled whenever possible, and
<br />non - toxic /non- hazardous materials will be used for road maintenance and backfill for
<br />reclamation on -site, rather than hauling to disposal sites off Hay Camp Pit. Waste materials
<br />are limited to: dust from baghouses, sludge from scrubbers, off - specification HMA
<br />(particularly from start-up and shut -down of the facility, and material which does not meet
<br />project specifications), excess HMA which cannot be used on the project or elsewhere, and
<br />HMA removed from hauling trucks. Normal solid waste (trash) and any materials which are
<br />potentially hazardous waste (such as petroleum- contaminated soil, soap, etc.) will NOT be
<br />used as backfill or for road maintenance but will be recycled or disposed of in accordance
<br />with county and state regulations.
<br />For the 2012 construction season, increased production of aggregates (estimated at
<br />up to 70,000 tons) will begin on May 1 and HMA production is expected to be needed for
<br />July and August of 2012, totaling approximately 55,000 tons. These numbers and dates are
<br />tentative and may vary based on contract awards and changes.
<br />The primary impacts are direct and indirect. Direct impacts include operation of the
<br />HMA facility with increased potential for dust, odor, noise, air emissions and water use and
<br />discharge. All these impacts are mitigated or eliminated by compliance with existing permits.
<br />All HMA facility equipment will be permitted in accordance with state and local requirements,
<br />including Special Use, High Impact, air quality, water quality, and fuel /chemical storage. No
<br />surface water discharge is anticipated. Setbacks both on -site and from adjacent receptors
<br />(nearby houses, businesses, and public areas) are adequate to provide mitigation of noise,
<br />odor, and similar impacts.
<br />Indirect impacts include increased traffic to and from Hay Camp Pit and on the Pit
<br />itself, as well as handling of materials and waste materials. As with indirect impacts, these will
<br />be mitigated in accordance with state and local law and DRMS guidance. Mitigations include
<br />increased watering and other maintenance of roads, proper storage, processing and
<br />recycling /disposal of waste, and other best management practices. This includes CDOT
<br />approval of traffic safety control plans as needed for haul on state highways, and similar
<br />county approvals.
<br />The agent for the landowner, LMN Properties, Mrs. Lavena Saunders, has been
<br />notified of this proposal and agrees to the Technical Revision. County permitting is presently
<br />underway, as is coordination with CDOT.
<br />Nathan Barton is my authorized representative for this request, and can be contacted

<br />this letter has provided all necessary information to proceed with the Technical Revision. The
<br />TR fee of $216 is attached.
