`� Attachment H ... previous calendar 12-month period. A copy of the 2008 inventory report for Bituminous Roadways' Shakopee asphalt plant is attached. You will notice on the attached report that there is nothing reported for Haz- ardous Air Pollutants (HAPs). Asphalt plants were originally listed as one of the types of sources for which the U.S. Environmental Protection Agency (USEPA) would be issuing regulations to limit emissions of HAPs. Those standards are called National Emissions Standards for Hazardous Air Pollut- ants (NESHAPs). The EPA has decided to drop asphalt plants from the categories of sources that need HAP regulations (i.e. asphalt plants are 'de- listed'). There are no NESHAPs standards for asphalt plants. Odor The most common odor detected at an asphalt plant comes from the hydro- carbons driven off the liquid asphalt cement. Overheating the materials dur- ing the drying process is the primary cause. As fuel has become more and more expensive, most owners and operators have become more aware of the cost of overheating materials and have learned to control temperature with greater precision. Warm Mix Pavement Technology The new asphalt plant that Bituminous Roadways proposes for its Roseville facility will utilize technology allowing the production of warm mix asphalt. � Warm mix asphalt technology decreases the hot mixed asphatt production temperature by 30 to 100 degrees Fahrenheit. This allows for reduced energy consumption, lowered emissions, and the elimination of visible smoke and odor. Noise There are a few common sources of noise emanating from an asphalt pro- duction facility. Some are derived directly from the asphalt production com- ponents, including the burner and exhaust stack. Others are generated from movement of the product, including trucks and loaders. Recent advance- ments in asphalt production equipment design have drastically reduced sound levels. It is often possible to participate in conversations using normal speaking tones while adjacent to most facility components at new facilities. The site must operate in compliance with State noise standards. Vehicles and equipment will operate with standard noise reduction features such as mufflers. Bituminous Roadways will invest significant resources into perime- ter berms and landscaping that will reduce noise emissions from the site. u APfinnative Aelioo F.mployer / Contractor Page 2 uf l
