. 8. Description of Ground Water. Surface Water. Air Qualitv: Ground Water The production operation employs a variety of screening, crushing, and conveying equipment, including loaders and dozers, The lubrication, fueling, and repair practices used to maintain the equipment are designed to eliminate petroleum products from ground contact. The Storm Water Pollution Prevention Plan (SWPPP) addresses practices for proper storage, hauling, and use of petroleum products, as well as inspection and response procedures, The pollution prevention practices addresses on-site management planning to minimize the opportunity for infiltrating water to carry contaminants to groundwater. Plant foremen perform site inspections throughout the operating period, Observations and conditions are reported for all applicable environmental programs, There may be on-site containment area for sediment before discharging water from the site, When and where necessary to prevent surface runoff from entering the Production Facility, contours of the site will be sloped away from the facility to direct surface water flow from the active Production facility, Surface Water . The Minnesota Pollution Control Agency's Storm Water Pollution Control Program regulates operations, Midwest Asphalt Corporation has an existing storm water plan for Production facility operations that employs Best Management Practices (BMP's) for pollution prevention, The management practices listed in the plan addresses both petroleum products handling and erosion control, including the on-property containment of storm water runoff for suspended solids control and containment areas with overflow pIpes, Air Quality The Minnesota Pollution Control Agency regulates crushing and screening operations at the site. The processing equipment is in compliance with the opacity requirements of the New Source Performance Standards and is permitted under the Aggregate General Permit. The general permit provides flexibility for using different processing configurations and various pieces of equipment, depending on the type of product being produced, It outlines production requirements, including record keeping, employee training, noncompliance prevention, and fugitive dust abatement and control measures that must be maintained for compliance with the permit. Records of daily, monthly and year-to-date production information is available for inspection, Water is used to supplement moisture for control of fugitive emissions, Water for dust suppression at this operation will be obtained from an on-site source, . 12
