NAPA’s Ecological Award competition, which started in 1971, recognizes excellence in asphalt facility operations.  NAPA selects the award recipients using rigorous criteria to evaluate the environmental friendliness of their operations.  Read more about the ecological practices of these winners in the September/October 2013 edition of Asphalt Pavement magazine.


WINNER - Ecological Award for Existing Facility
Payne & Dolan Inc., Vienna, Wis.
Control #6

EE4-PayneDolanPayne & Dolan’s 17-year-old Vienna Control #6 plant is located near Madison, Wisconsin, and is a next-door neighbor to the company’s Vienna Quarry, which supplies all the aggregate for the plant. Fitted to produce warm-mix asphalt, the plant also uses reclaimed asphalt pavement and tear-off asphalt roofing shingles in it mixes, preserving natural resources while making a high-quality product.


In addition the plant uses only biodegradable release agents on its shovels, rakes, conveyors, and other equipment.


Payne & Dolan also takes strides to be build good neighbor relationships by sweeping the streets, and cleaning the driveway and plant regularly. Neighbors are notified in advance of nighttime paving which would require extended plant operations hours.


WINNER - Ecological Award for Existing Facility
S.T. Wooten Corp., Wilson, N.C.
Wilmington Asphalt Plant

EE5-STWootenS.T. Wooten Corporation’s seven-year-old Wilmington, North Carolina, asphalt plant converted two years ago to producing 90 percent warm-mix asphalt. The plant uses a gas analyzer to control combustion efficiency and recycles all particle emissions collected in its baghouse back into the asphalt mix.


Rainwater runoff is directed to a grass pond, where water is filtered through the grass and soil. The driveways and plant area are paved to control dust wash down. The Wilmington plant also uses a bucket sweeper to remove additional material from the driveways.


S.T. Wooten Corp. reclaims asphalt pavement and roofing shingles and recently trained an internal energy manager to conduct plant energy audits and to implement additional best practices.


The plant is a good neighbor and is surrounded by grass, trees, and plants, including palms and native shrubbery at the plant’s entrance.


WINNER - Ecological Award for New Facility
Lakeside Industries, Lacey, Wash.
Durgin Road Plant

EN3-LakesideThe Durgin Road plant operated by Lakeside Industries in Lacey, Washington, is a 300-ton-per-hour asphalt plant that hosts daily pollution control inspections, uses warm-mix technology, and strives to conserve natural resources. It does this by using a natural-gas dryer burner and a variable-frequency drive on its baghouse, which helps eliminate large electrical demands. Lakeside also uses a gas analyzer to control combustion efficiency.


The company controls rain runoff through water-treatment ponds with infiltration, as well as by dispersing monitoring wells throughout the plant. Using Best Management Practices to control dust washdown, the entire site is paved and a water truck is used to wet the site in dry months.


WINNER - Ecological Award for New Facility
Tilcon New York Inc., an Oldcastle Materials Co., Wharton, N.J.
Keasbey Asphalt Plant

EN2-TilconNYTilcon New York, an Oldcastle Materials Company’s one-year-old Keasbey asphalt plant replaced two less efficient plants in Wharton, New Jersey. Since coming into use, the plant has recorded lower maintenance, labor, electricity, and mobile equipment costs. An increase in reclaimed asphalt pavement processing at the site has also reduced hauling costs for virgin aggregate. Also, a water-injection system is used to produce foamed warm-mix asphalt at the plant.


The new site uses a gas analyzer to control combustion efficiency and a combination baghouse, flue-gas recirculation system, and blue-smoke capture system for emissions control.


The plant also has an automatic ticketing system was put into place, reducing the time it takes trucks to get a ticket from 3 minutes to 45 seconds, which helps reduce emissions and fuel used while idling.
