Brownfield Braintrust Podcast with Matt Winefield: Vapor Intrusion Mitigation Systems (VIMS) with Justin Conaway of Terra-Petra Environmental Engineering

The most recent episode of the Brownfield Braintrust Podcast, host Matt Winefield speaks with Terra Petra’s own Justin Conaway

Episode Details From Brownfield Braintrust Podcast:

In our current Brownfield Braintrust Podcast, Matt Winefield of Winefield & Associates, Inc. sheds light on Vapor Intrusion Mitigation Systems (VIMS) with the help of Justin Conaway, Vice President and General Manager of Terra-Petra Environmental Engineering. Given evolving soil vapor mitigation standards, VIMS are currently much more prevalent than just three years ago. It is unlikely one can acquire, for example, a former dry cleaner site (with PCE releases), run a vapor extraction system, and then pour your foundation. The lead agency will likely specify a VIMS that operates for the life of the new building. Justin explains the three most common VIMS technologies now utilized.

Brownfield Braintrust Podcast w/ Matt Winefield, Jeremy Squire & Jay Tufano: SWRCB Resolution 92-49

Re-Post From

And now for a brownfields topic that, at first, seems esoteric but will actually impact just about every facet of site cleanups in California. We get into the weeds about proposed changes to Water Code Resolution 92-49. This resolution conveys policies and procedures to the State Water Board and Regional Board officials relating to the investigation and cleanup of discharges into groundwater, surface water and even soil. The topic was much too detailed and cerebral for Matt to tackle alone, so he invited two special guests: Environmental attorney Jay Tufano, Partner at Ring, Bender, LLP and environmental engineer Jeremy Squire, Vice President at Murex Environmental, Inc.

Terra-Petra Team in Attendance

Terra-Petra’s Vice President, Justin Conaway, Director of Field Operations, Dan Valdez, and Senior Environmental Engineer Bahar Amoli attended, representing our Environmental Engineering Division.

They also enjoyed the outdoor highlights in the beautiful Yosemite National Park, including sight seeing in and around El Capitan, Half Dome and hiking Mount Hoffman.

Justin Conaway commented, “This conference offers such a great environment to connect with our clients on a deeper level by inviting spouses, children and dogs to attend. Getting to know some more personal things about the people we work with really humanizes us and allows for a more comfortable natural environment to socialize. This conference is a must-attend for me every year for these reasons.”

Rampart Mint Welcomes 22 Formerly Homeless People

Rampart Mint Welcomes 22 Formerly Homeless People

Great article from below about a this project in the Rampart Village area of Los Angeles.  Terra-Petra is very proud to have been a part of this project.  We designed and inspected the methane mitigation system during development, working with both the West Hollywood Community Housing Corporation and KFA.

West Hollywood Community Housing Corporation is proud to announce the opening of Rampart Mint, an all-new, affordable apartment community for formerly homeless individuals. Located in the Rampart Village area of Los Angeles, Rampart Mint includes 22 permanent supportive housing units and one unit for an on-site resident manager.

Co-developed with Affordable Living for the Aging, Rampart Mint is built on city-owned land. ALA will provide the on-site building management and has decades of experience working with special needs populations.

“When residents begin to move in, it makes the project real for us,” said Matt Mason, WHCHC’s director of real estate development. “We’re all very proud to be able to create quality affordable apartments for L.A.’s most vulnerable community members.”

The KFA-designed building includes a spacious community room with kitchenette, a computer area, a rooftop garden with amazing views of the city, a building manager’s office and social services office.

“This has been a labor of love,” WHCHC Assistant Project Manager Rachel Peled said. “These last few days putting the final pieces in place, knowing their life-changing value, was electric.”

Rampart Mint was built by Dreyfuss Construction. Pioneering universal design principles have been incorporated so every unit accommodates those with and without physical limitations. Residents can truly age in place without fear of displacement.

“I am so pleased to see the Rampart Mint project come to life,” said Los Angeles City Councilman Mitch O’Farrell, 13th District, who represents parts of the Westlake neighborhood on the Los Angeles City Council. “My office has actively supported this project from the beginning, and I welcome 22 apartments for chronically homeless individuals with special needs in the district I represent. I look forward to continuing our work with WHCHC to create more quality affordable housing, including supportive housing, for our most vulnerable.”

Vapor Intrusion Mitigation System Design And Installation – Santa Fe Springs, CA

Terra-Petra’s Environmental Engineering Division has partnered with a Los Angeles REOC and investment management firm to design a comprehensive Vapor Intrusion Mitigation System (VIMS).

The new development, located in Santa Fe Springs, CA, will consist of a tilt-up industrial warehouse building, on grade, with an approximate building footprint of 150,500 SF. The gas vapor mitigation system shall be designed in accordance with a site specific Phase II Environmental Site Assessment report, and in accordance with the Vapor Intrusion Mitigation Advisory published by the C.A. EPA Department of Toxic Substances Control (DTSC) dated October 2011 (Cal/EPA 2011a, 2011b).

Vapor Intrusion Consulting, Testing And Monitoring – San Diego

Soil Gas Investigation Los Angeles, CA

In early January, Terra-Petra performed a soil gas investigation (SGI) in Los Angeles, CA, in accordance with LADBS guidelines (Information Bulletin Ref. No. 91.7104.1, P/BC 2002-101) under Terra-Petra’s LADBS Methane Testing Lab License #10224, for a major property developer.

We are pleased to continue the partnership to provide mitigation design and consulting services. The project consists of the construction of a new slab on grade warehouse building with a building footprint of approximately 169,253 SF.

There are as many as six (6) oil wells on this property, three of which may fall under the footprint of the new building. The scope of work includes methane mitigation plan design (passive system) and permitting, methane gas detection system design (active system) and permitting, and construction administration support.
