2016 Ecological Award

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 July/August 2017 edition of Asphalt Pavement magazine. 

 

WINNER — EXISTING PLANT
The Lane Construction Corp.
West Columbia, S.C.
West Columbia Facility

The Lane Construction Corp.'s West Columbia facility is nine years old and operates year round. The facility consists of a drum mix asphalt plant and a maintenance area. The plant has a capacity of 500 tons-per-hour with three 200-ton storage silos and2016-EE2 Lane Construction Corp 2 a Quality Control lab. Operations are year-round.

 

"Our facility is located on the site of an old mining pit and is prone to erosion," Lane Construction Corp. Plant Manager Lee Barrack said. "We control the erosion by grassing embankments, adding plants, and using swales to limit damage and control the water."


Swales are used to direct water across the site. The pond slopes are grassed, and riprap was added last spring to increase stabilization. The holding pond allows solids time to settle out before water leaves the site. These efforts have helped to minimize on-site erosion and keep turbidity levels low.


Wash water is managed and recycled. There is an equipment wash on-site with a closed-loop system containing an oil-water separator. After the water is separated from the oil, the water is recycled and reused in the equipment wash. The remaining oil is stored in a tank, which is emptied by a recycling company.


In addition to water, Lane uses reclaimed asphalt pavement (RAP); it's incorporated into all of the mixes. Stockpiles of fine, coarse, and RAP aggregates are stored onsite to supply the plant. The company saves energy by using warm-mix technology in its Open Grade Friction Course interstate paving projects.


The company also has containment areas around the liquid asphalt tanks to protect the site in the event of a tank leak, and protocols are in place to control fugitive dust, exhaust emissions, and noise.
"Lane recognizes that dust, odor and noise generated from operations can be a nuisance. To mitigate these issues, we have Good Neighbor and Preventing Nuisance policies," Barrack said. "Employees are trained on these policies so they can make every effort to reduce any impact on the surrounding community."

 

WINNER — EXISTING PLANT
Pike Industries Inc., an Oldcastle Materials Co.
Belmont, N.H.
HMA P-727

Pike Industries, an Oldcastle Materials Co., built its Hooksett, N.H. plant and quarry two years ago. Located off of Interstate 93, it is equidistant between the cities of Concord and Manchester. The 400-ton-per-hour counterflow drum warm-mix asphalt 2016-EN1-PikeIndustries-HMAP 727 1plant not only saves energy by producing asphalt mix at lower temperatures than traditional hot-mix asphalt, its location ensures lower trucking fuel and related costs to work zones.

 

To ensure significant energy savings Pike Industries chose premium high-efficiency motors, which are designed to significantly save energy over that which is spent by conventional motors.


"By using premium high-efficiency motors, our energy savings are 50 percent over what it would take to operate conventional motors," Jonathan Oakes, Pike Industries' Vice President of Asphalt, said. "We save about 35 cents per ton of asphalt mix."

 

In addition to saving energy by operating a warm-mix asphalt plant, using premium high-efficiency motors, and saving fuel by locating the plant strategically between the state's two biggest cities, Pike Industries also uses green practices to control fugitive dust and wastewater.

 

"The plant yard is swept and vacuumed weekly, and a water truck sprays continuously to control fugitive dust," said Oakes. A designated wash down area contains the water, and wastewater from the plant yard drains internally into a setting pond. The closed system returns the water to the plant.

 

FINALIST — EXISTING PLANT
Barrett Paving Materials Inc.
Watertown, N.Y.
Watertown Drum Plant

Barrett Paving Materials Inc.'s Watertown facility is six years old, with a 400 ton per hour drum plant. The facility follows a variety of energy savings, fugitive dust prevention, and wastewater management practices.2016-Eco-Barrett 9

 

"We have pride in our plant site," Plant Manager Scott Lockerbie said. "Our goal is a clean, safe job site."

 

Barrett Paving Materials uses warm-mix asphalt foaming technology, which helps lower the temperature needed to produce high-quality asphalt mixtures. The company also uses stockpile management to lower energy use associated with drying reclaimed asphalt pavement (RAP). The RAP is only processed as it is needed. These energy saving management strategies have helped make the Watertown Plant stand out as one of the company's most energy-efficient plants, based on BTUs/ton of asphalt mix.

 

The company follows its Stormwater Pollution Prevention Plan to ensure that wastewater is responsibly managed so that it does not spread pollutants or cause erosion. The entire plant and truck exit route is paved. The pavement helps keep the plant site clean, and the landscaping and regular painting ensure the plant's two 200-ton silos help prevent the plant from appearing as an eyesore to the community.

 

In addition to maintaining a clean, attractive plant site, Barrett Paving Materials makes a point to be a good neighbor. Barrett Paving Materials furthers its reputation for environmental responsibility and participation in the community by sponsoring an annual roadside cleanup and supporting its more than 100 employees to give time at community events that are important to them.
