2.1.1 Narrative
The removal
action involves the removal of contaminated soils up to two feet below ground
surface found on site. Hazardous substances will be profiled, packaged, and transported
to off-site disposal facilities that are in compliance with the EPA Offsite
Rule. All waste streams will be profiled and disposed of appropriately. Contaminated soil will be excavated and
backfilled. The property will be graded
and stabilized.
During this reporting period, site preparations were completed to facilitate the proposed actions in the Action Memorandum. Heavy rain in the area during the week of January 4th (01/04-09) has impacted site operations.
2.1.2 Response Actions to Date
On 12/16/15, EPA START (3 members) mobilized to the site and met with EPA ERRS contractors (4 members) and an EPA OSC. EPA START deployed VIPER with four DataRAMs to monitor the air for particulates, while ERRS contractors cleared shrub with a heavy duty brush cutter. Vegetative debris and empty drums were stockpiled at the center of site for future disposal.
City of Wylie officials arrive on site to discuss the use of a private road running parallel to the west of the site. City of Wylie officials stated they would take responsibility for any damages caused on the private road and repair the private road to the original condition.
On 12/17/15, EPA START (1 member) arrives on site to establish excavation grids using a Geographic Positioning System device. A total of 32 grids were establish ranging in size of 40ft x 40ft, 60ft x 80ft, and 100ft x 100ft. ERRS crews continued to clear shrubs and brush on site, and collected a composite waste characterization sample of the 32 grids.
During the period of 1/05/16 to 1/08/16, ERRS contractors (7 members) installed 8ft x 16ft wooden loading pads with ¾ inch gravel laid on top near the southwestern corner of the property, designate the area as the Support Zone. The Support Zone consists of an 8ft x 20ft storage container, 10ft x 30ft Command Post, two generators, two portable restrooms with a hand washing station, and a parking zone for site personnel. Heavy equipment on site consists of a front shovel excavator, 9 yard dump track, and a skid steer loader. No excavation activities occurred due to an overnight 9 inch rain event on 1/05/16, site conditions improved by 1/08/16.
On 1/09/16, ERRS contractors began excavation activities on the north side of the site, grid R01 and B01, both grids were excavated to 6 inches below ground surface. Excavated soil is staged north of the Support Zone for anticipated transportation on 1/13/16. An estimated 100 cubic yards of contaminated soil has been excavated during this reporting period, excavation of B01 will continue on 1/11/2015. No air monitoring was deployed on site as soil conditions continue to be saturated from the previous rain event.
ERRS collected a composite waste characterization
sample of the 32 grids. The composite sample passed TCLP, site was deemed as
Class 2 Non-Hazardous Waste.
An estimated 100 yards3 of
contaminated soil from 1 ½ grids (R01 and half of B01) has been excavated and
staged north of the Support Zone for transportation and disposal at a CERCLA approved disposal facility.
