Brownfields investments are risky. The new, scientifically suspect vapor intrusion criteria floating around CalEPA make these investments even riskier. Winefield & Associates must deliver acceptable returns to its investors, notwithstanding our goal to bring blighted sites to productive use. Unfortunately, the use of the 0.03 Attenuation Factor by Southern California regulators has forced W&A to kill two brownfield redevelopment projects. One of the projects would have promoted jobs in South LA, while the other project would have initiated redevelopment in Gardena. As CalEPA continues to use bad science to roll out unnecessary remediation goals, they seem oblivious to real-world implications of their actions. For example, the two sites just referenced will now continue to be blighted and underutilized indefinitely. Thanks, CalEPA!

The Center for Creative Land Recycling is the nation’s premier brownfields non-profit. In its March 12, 2019 transmittal to DTSC, CCLR urged the DTSC to solicit public comment on the technical and policy considerations surrounding the proposed VI screening levels. CCLR acknowledges the devastating impact CalEPA’s proposed guidance document could have on construction and development statewide. Read CCLR’s letter to DTSC here.

Winefield & Associates has developed a document for regulators, real estate investors, and other interested parties to warn city officials about the new vapor intrusion guidance. Most cities are not currently aware of CalEPA’s activities. Cities are depending on tax revenue from new developments, and are combating an incredible homelessness challenge; CalEPA’s new Environmental Screening Levels will thwart both programs. Please feel free to use the attached template to share concerns with your mayor, city council officials, and economic development managers

December 2018 – These documents were developed for the Air & Waste Management Association Vapor Intrusion, Remediation, and Site Closure Conference of December 6, 2018 in Phoenix Arizona. The median (i.e., 50th percentile) and 95th percentile values for AFs calculated from all filtered data in this study are 0.00012 and 0.0019, respectively. We urge the reader to download and share this data with the regulated community.

The California CUPA Conference takes place Monday, February 25th through Thursday, February 28th in Anaheim.
