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.

Soil Management Plan Implementation – Richmond Oil Field

Terra-Petra recently mobilized to a development within the Richmond Oil Field in Yorba Linda, CA after the grading contractor working on the site encountered what they described as “black colored material”. Soil that carries these characteristics is suspected of being impacted by petroleum-contamination, pesticide impact or other hazardous materials and needs to be tested by a laboratory to verify the actual presence of contaminants and at what concentrations.

In this particular case, Terra-Petra elected to run the following tests on the soil samples we collected from the site under a strict chain of custody protocol.

  • EPA 8260B by 5035 – Volatile Organics by GC/MS + Oxygenates/Gasoline Range Organics
  • EPA 6010B by 3050 – Title 22 CAM 17 Trace Metals by ICP-OES
  • EPA 7471A – Mercury by Cold Vapor Atomic Absorption
  • EPA 9045C – pH
  • EPA 8270C-SIMS Polynuclear Aromatic Hydrocarbons

With the laboratory results Terra-Petra was able to conduct a site assessment to delineate the potentially impacted area, which was approximately 90’-180’ .  The Soil sampling was implemented in accordance with the site-specific Soil Management Plan (SMP), which is essential for any development where impacted soils may be encountered. Within an SMP should be a section describing the specific response/remedial actions that will need to be carried out for any impacted soils.

Numerous agencies can become involved with remedial actions for projects in Orange County in particular. For example, the Orange County Health Care Agency (OCHCA) and Orange County Fire Authority as well as the local planning department will be notified and involved in such matters. Additionally, the Regional Water Quality Control Board, the California Department of Conservation, Geologic Energy Management Division (CalGEM) and South Coast Air Quality Management District may become involved until a no further action status is attained.

In the coming days and weeks Terra-Petra will be drafting and submitting a Work Plan to carry out the remedial activities under the oversight of the local agencies involved.

Terra-Petra Completes 2201 E. Cerritos Ave. Project for Western Realco

Southern California environmental engineering firm, Terra-Petra recently wrapped up its PMP project for Newport Beach-based developer Western Realco LLC on 2201 E. Cerritos Ave. in Anaheim, California.WRlogo

Los Angeles, CA (PRWEB) April 11, 2014–Terra-Petra was pleased to have been a part of a very successful project with Western Realco, LLC in Anaheim this last month. Terra-Petra carried out the Property Management Plan (PMP) for the site during grading activities ahead of the construction of the building’s foundation, given that TPH and VOC-impacted soil might be encountered during site grading and building construction activities.

As a precautionary measure, the building on site was equipped with an active soil gas mitigation system, complete with a sub-slab venting system, vapor barrier and mechanical extraction fans. Based upon Terra-Petra’s expertise, the company was responsible for serving as the Construction Quality Assurance and Construction Quality Control (CQA/CQC) Officer for Western Realco throughout the construction of the soil vapor mitigation system. Each and every item of the approved plans was inspected and under the watchful eye of Terra-Petra’s inspection team. The system was installed with minimal issues. Terra-Petra was there every step of the way to document and ensure compliance with all project specifications.2201ECerritos

During the sale of the property, Terra-Petra also drafted and implemented an Operations and Maintenance (O&M) Plan for Western Realco that provided the determining mass emissions output for the active vent risers as was required in the project specifications. Test results were finished in record time in order to ensure that the work was completed within the due diligence phase of sale upon project completion.
