Folsom site contaminated by jet fuel to be cleaned up, paving way for park and nearby housing

At a public forum Wednesday evening at the Folsom Community Center, DTSC project manager Peter MacNicholl pitched about 20 skeptical residents on the specifics of the cleanup plan, which aims to remove dangerous toxic chemicals like trichloroethylene and perchlorate from the soil and groundwater.

. . . 

At the public forum, vocal critics expressed doubt about the thoroughness of the cleanup, DTSC safety standards and the effectiveness of a fence in keeping people away from toxic fumes. Rob Burness, a member of the Environmental Council of Sacramento, also worried about the impact to wetland wildlife, which MacNicholl acknowledged was unavoidable.

“We need to have an aggressive plan that goes beyond the fencing and just removal of the land, the most contaminated soil,” Burness said during public comment. “It needs to deal with potential that there will still be trespass, that wildlife will still be impacted, and the vapors will impact the surrounding parkland.”

Neighborhood Planned for Toxic Waste Site in Folsom

June 12, 2018

How do you think the Aerojet Area 40 Toxic waste site in Folsom should be cleaned up before it is developed into a park, open space and residential area?

A Public Meeting to Review and Comment on the Remedial Action Plan for the cleanup and development of the Aerojet Area 40 Toxic Waste site, which is South of Highway 50 will be held:

June 20 from 6-8 pm,
Folsom Community Center,
Western Conference Room,
52 Natoma Street, Folsom

South of highway 50 just east of Prairie City Road, lies Aerojet Rocketdyne’s “Area 40”, a hazardous waste site waiting be cleaned up. Folsom and local developers are planning a 48-acre park with housing nearby within the Folsom Planning Area at the location of Area 40. A 26-acre “open space” will be fenced off until extremely high soil vapor levels drop to lower levels.

The Department of Toxics Substances (DTSC) released the proposed cleanup plan in May, and a Public Meeting will be held June 20 in Folsom.

While Aerojet Rocketdyne leased this land their industrial activities included separating solvents from propellant-solvent mixtures and open burning of laboratory wastes, propellants, kerosene fuel, and flammable liquids.

Chemicals identified within Area 40 soils and soil vapor were: dioxins and furans, metals, perchlorate, semi- volatile organic compounds and volatile organic compounds. Chemicals identified in groundwater were perchlorate, trichloroethylene (TCE), tetrachloroethylene (PCE), and additional volatile organic compounds.

The proposed cleanup plans are to remove 31,100 tons of contaminated soil from two areas on the site. Note that soil vapors move from the soil into the air. Extremely high levels of volatile organic compounds are in the shallow groundwater. The cleanup plans include measures to require vapor mitigation systems to move chemical vapors from under potential new housing.

How thorough will the cleanup be for the proposed new Community West Park near Prairie City Road? For the open space area north of the park? For the single-family high-density homes just north of the site, and for the commercial and multi-family units to the south?

Levels of contamination: The Remedial Action Plan (RAP) for Area 40 says that the site poses unacceptable risk to human and ecological health, which is true. However, the RAP does not mention that the levels of TCE in shallow groundwater, soil gas and even outdoor air are among the highest observed in California. The site has up to 120,000 μg/L TCE in shallow groundwater, which is 24,000 times the Maximum Contaminant Level (MCL) of 5 μg/L TCE. The site has up to 268 million μg/m3 TCE in soil gas, which is 8 million times the EPA default screening level for protecting residents from TCE vapor intrusion into indoor air. The levels of TCE are so high on portions of the site, that levels of TCE in outdoor air 4 foot above the ground pose a risk for fetal heart defects. Levels of TCE are likely to be even higher for infants or small children breathing closer to the ground and individuals laying or picnicking on the ground.

The City of Folsom and the developers are focused on whether the park can go into the proposed area. The risk assessment for human health is based on limited park use.

During the cleanup additional contamination may be found, which could change the scope or nature of the cleanup.

City will use money to repay developers for public infrastructure costs, though litigation could complicate things…A lawsuit filed by a group of residents calling themselves the East Sacramento Partnerships for a Livable City alleged that the city’s environmental impact report failed to adequately analyze or diminish the impacts of the infill housing project, including its location near a former landfill and proximity to freeway pollution, and the projected increase in residential traffic.
