SUBJECT: PLANNING / BUILDING DEPARTMENT NOTIFICATION OF CASE CLOSURE OF SMi'o SITE #668a97, ONE 400-GALLON HEATING OIL UNDERGROUND STORAGE TANK (UST) AT THE WILLIAMS RESIDENCE, 1428 ALVARADO AVENUE, BURLINGAME, CALIFORNIA Dear Ms. Monroe: The enclosed case closure letter is a result of intensive review by San Mateo County Groundwater Protection Program (GPP) staff with concurrence from the Regional Water Quality Control Board staff. San Mateo GPP staff have determined that the water quality objectives of the San Francisco Bay Regional Water Quality Control Board have been satisfied. However, an unknown quantity of residual hydrocarbon-impacted soil remains at the site. Should any change in use of the property or development of the subject site occur which may impact these soils or groundwater, city building departments must notify the Environmental Health Division for approval pursuant to Government Code Section 65850.2. County oversight costs for management of contaminated soil or groundwater will be billed directly to the current property owner. Should you have questions, you may reach me at (650) 599-1079.
