Sacramento, California Phase I Environmental Site Assessments

Partner provides both local and nationwide Phase I Environmental Site Assessments. Our reports are performed to meet the standards of ASTM E1527-21 or customized to meet individual client or agency lenders’ (Fannie Mae, Freddie Mac) requirements. The Sacramento staff are familiar with the blend of metropolitan areas, industrial areas, suburbs, and agricultural areas that make up the Central Valley.

Performing Phase I Environmental Site Assessments (ESAs) in California is a little different than in other states. The Golden State has lived up to its name in the world of real estate as real estate investors have done quite well in the past 50 years. Arguably one reason for real estate appreciation is that real estate in California is supply restricted and environmental regulation is one of many causes for the supply restrictions.

When selecting an environmental consulting firm to perform your Phase I Environmental Site Assessment in California, you should either choose a California firm or at least a non-California firm that is intimately familiar with CA regulations.

Solutions

A Phase I ESA in Sacramento, California will typically involve the following steps: Site Reconnaissance: An environmental professional will visit the property to observe current conditions and identify any potential environmental hazards. Records Review: The environmental professional will review historical records, such as aerial photographs, Sanborn maps, and city directories, to identify past uses of the property and any potential environmental hazards. Regulatory Database Search: The environmental professional will search regulatory databases to identify any known environmental violations or hazards on or near the property. Interviews: The environmental professional may interview the current and former owners/operators of the property, as well as government officials, to learn more about the property's history and any potential environmental hazards. Once the Phase I ESA is complete, the environmental professional will prepare a report that documents their findings and conclusions. The report will identify any Recognized Environmental Conditions (RECs) that were found on or near the property. A REC is a condition that has the potential to cause environmental contamination or liability.

Frequently Asked Questions

The timeframe can vary, but it often takes a few weeks to complete a Phase I ESA, depending on the complexity of the site and the availability of historical information.
A Phase I ESA typically includes a review of historical records, interviews with property owners and occupants, a site inspection, and a report detailing findings and recommendations.
Common concerns include potential soil and groundwater contamination, hazardous waste history, nearby chemical storage facilities, or the presence of underground storage tanks.
Phase I ESAs in California are often conducted in accordance with ASTM E1527-13 standards, and they must comply with state and federal environmental regulations.

Digging Deeper

 

Registered Environmental Professional

California is one of the only states that register environmental professionals. ASTM E1527-05 requires that an environmental professional perform the Phase I Environmental Site Assessment; therefore, a quality-sensitive client will ask if their CA environmental consultant is a Registered Environmental Assessor (REA).

Regional Water Quality Control Boards

In most states, the regulations are statewide rules with maybe some variations for cities and counties. In California, the State Water Board grants a lot of power and autonomy to the Regional Water Quality Control Boards. The regional water boards are organized generally by watershed and may split counties. Water boards may have very different regulations. For example, the San Francisco Bay Regional Water Quality Control Board developed Environmental Screening Levels (ESLs) for soil and groundwater contamination, whereas the Los Angeles Regional Water Quality Control Board uses different screening levels including Soil Screening Levels, CHHSLs for soil-gas (see below), and Maximum Contaminant Levels (MCLs) for groundwater.

CHHSLs

The California Environmental Protection Agency (EPA) published the California Human Health Screening Levels (CHHSLs) in 2005. The CHHSLs provide the user with a chemical-specific look-up table for what levels of soil gas or indoor air concentrations represent a threat to human health. CHHSLs are not intended to be regulatory numbers but are often treated as such. CHHSLs are also famously conservative. You need an environmental consultant doing your Phase I ESA that knows how to interpret soil gas and indoor air data in relation to CHHSLs and this requires a lot of California experience.

CUPAs

Certified Unified Program Agencies (CUPAs) have a lot of power in California. CUPA are city or county agencies that have been more or less deputized to handle certain regulatory functions. An example of a CUPA is the City of Los Angeles Fire Department, which oversees releases from underground storage tanks (USTs), termed leaking USTs or LUSTs. To do proper regulatory due diligence during a Phase I Environmental Site Assessment your environmental professional must understand the California CUPAs.

CEQA

The California Environmental Quality Act (CEQA) is California’s equivalent of the National Environmental Protection Act (NEPA). A Phase I Environmental Site Assessment sometimes has to deal with CEQA/NEPA issues like wetlands, endangered species, and/or historical resources as additional scope items.

The above issues are really statewide issues. Some of California’s largest cities and counties have unique regulations too, and you can really get some complex jurisdictional issues.

In the Bay Area and Northern California, there are three regional water boards to be familiar with: San Francisco (the main district covering the nine Bay Area counties), North Coastal, and Central Coastal water boards. These three water boards are sometimes referred to as the TriRegional Water Boards.

There are many local CUPAs including the City and County of San Francisco Public Health Department, San Mateo County Environmental Health, Santa Clara County Environmental Health, Alameda County Environmental Health, Marin County Department of Public Works, Sonoma County Office of Emergency Services, Napa County Department of Environmental Management, Contra Costa County Health Services Department, and Solano County Environmental Health Department. Larger cities within these counties such as Oakland, Santa Rosa, the City of Santa Clara, and Fremont have fire departments that act as the local CUPAs.
