ERC was hired as the General Contractor for this project to remediate the former service station. Gasoline underground storage tanks (USTs) were previously removed however historical releases had contaminated both soil and groundwater at the site. The remedial activities for this project included excavation and off-site disposal of petroleum contaminated soils, as well as the addition of oxygen-releasing amendments to the exposed groundwater in order to stimulate microbial growth and enhance contaminant degradation. Over 7,500 tons of impacted soil were excavated and hauled off site to a Subtitled D facility for disposal. During the project ERC encountered an additional unknown UST which was also disposed of. The site was restored by the placement of topsoil, seeding & mulching.

STREAM, BANK STABILIZATION

By Chris McGovern

Akron, Ohio

Worked with engineers and landscaping firm to repair country club stream on holes 4 and 10 that were damaged by a volatile adjacent stream. We used matting to ensure the surrounding area was not damaged by our equipment as we excavated and widened the creek. Stream restoration, we rebuilt the channel and waterfall using placed rock and added j-hooks and v-weir structures to control the future stream water flow. In order to stabilize the banks (Bank Stabilization) and existing golf course greens we installed compost filter socks impregnated with aggregate and seed, and by installing weep holes in the existing sheet piled wall.

DAM REMOVAL, GOB FIRE

By Braeden Hurley

Coal Gob Fire Quenching – Wellston, Ohio

Removal of a dead lake from a former coal mine in Southern Ohio. While working on removal of a dead lake we uncovered a burning gob fire. We moved 45,000 cubic yards of cut to fill and cut to waste, installed 36" reinforced concrete pipe to relieve the dam, and dewatered over 100 million gallons. We moved over 16,000 cubic yards of earth to expose the gob fire, we extinguished,quenched, and then capped the site. To complete the project we seeded and mulched, returning the area to a grassy field as designed and nature intended.
