Thousands of truckloads of contaminated soil are being removed from land in the Homestead Development off Pitt School Road.

DIXON, CA (MPG) - You might think that the bulldozers were digging out a mountain of soil to put in a lake in the newer Homestead development off Pitt School Road, but the project involves actually digging out a huge area of former farmland that has soil contamination.

Village Green residents as well as neighboring Homestead developments received warnings of the contamination a few months ago and the work has officially begun.

The notice explained that the California Department of Toxic Substances Control (DTSC) has a mission to protect California’s people, communities, and environment from toxic substances, to enhance economic vitality by restoring contaminated land, and to compel manufacturers to make safer consumer products.

They sent the notice to let the community know about the proposed cleanup at Operable Unit 3-East (OU-3 East) of the SW Dixon Plan - Harvest Site (Site). OU-3 East is located generally south of West A Street and west of Pitt School Road in the City of Dixon.

The cleanup activities will include excavating approximately 56,000 cubic yards of soil contaminated with organochlorine pesticides and transporting to a permitted disposal facility. Construction equipment such as backhoes, excavators, loaders, and trucks will be used for excavation and hauling. An estimated 4,500 to 4,700 truckloads of soil are expected to be off hauled from the Property. Work began at the end of April and will require up to six weeks.

Excavation, soil loading, and trucking will take place Monday through Friday from 7 a.m. to 6 p.m. on weekdays (excluding holidays.)

As trucks exit the Property, they will take the following route: Exit the site onto West A St; Head east on West A Street toward Pitt School Rd; Tum right onto Pitt School Rd; Tum left onto Midway Rd; Turn right at 1st cross street onto CA-1 13 S; and enter 6426 Hay Road.

Safety measures include perimeter fencing will be installed at the Site. Air monitoring equipment will be deployed upwind and downwind of excavation areas to monitor dust emissions during cleanup activities. Water will be used to wet soil to minimize dust, as necessary. 

Stockpiles will be covered with plastic sheeting and truck loads will also be covered with tires cleaned before leaving the site. Excavation activities will be temporarily suspended if dust control measures are not effective.

Vehicle speed on-site will be limited to a maximum of 5 mph.
