Redevelopment at the Site

The 35-acre Sola Optical USA, Inc. (Sola Optical) Superfund site is located in Petaluma, California, about 30 miles north of San Francisco. Sola Optical manufactured ophthalmic lenses at the site from 1978 through 2001. The facility included one manufacturing building and an adjoining administration office building. In 1982, the State identified acetone in an on-site well. Later, Sola Optical reported contaminated soil next to six underground solvent storage tanks at the facility. In 1985, Sola Optical removed the underground storage tanks and surrounding soil and confirmed the existence of contamination in shallow groundwater underneath the site. EPA added the site to the Superfund program’s National Priorities List (NPL) in 1990. Sola Optical treated groundwater at the site from 1988 to 1997. In 2007, EPA agreed to allow the groundwater to recover naturally. In 2012, EPA confirmed that the groundwater had achieved the cleanup standards. EPA removed the site from the NPL in 2013. In 2000, RNM Cader, LLC, purchased about 11 previously-undeveloped acres in the southwest portion of the site for development. Between 2005 and 2010, RNM Cader constructed an asphalt parking lot and four building pads. The owner of the remaining 24 acres of the Sola Optical property sold the property and buildings to Kland, LLC in 2002. Two commercial tenants currently occupy the buildings on the site facility parcel. Petaluma Poultry’s administrative office occupies one building, conducting sales and distribution of poultry. Reynolds Packaging conducts storage and distribution of food packaging materials from the original manufacturing building.

Activity and Use Limitations

At this site, activity and use limitations that EPA calls institutional controls are in place. Institutional controls play an important role in site remedies because they reduce exposure to contamination by limiting land or resource use. They also guide human behavior. For instance, zoning restrictions prevent land uses – such as residential uses – that are not consistent with the level of cleanup. For more background, see Institutional Controls.
