Phase I Environmental Site Assessment Spotlight: HREC

One of the major changes to the Phase I Environmental Site Assessment ASTM standard (E1527-13) is the enhanced definition of a REC (Recognized Environmental Condition).  ASTM added the term CREC (Controlled REC), in addition to the previously defined REC and HREC (Historical REC).

An HREC property is one that was previously deemed to have potential or actual contamination, but has since undergone remediation that meets current standards of cleanup.  An HREC site is not subject to any land use restrictions.

Case Study

Gabriel was conducting a Phase I in Chicago of a former machine IEPA-logoshop. The site was identified on the regulatory database search as an SRP (Site Remediation Program) site.  SRP is a voluntary cleanup program run by the Illinois EPA.  The IEPA is authorized to issue No Further Remediation (NFR) letters to the Remedial Applicants who have successfully demonstrated, through proper investigation and possible remedial action, that environmental conditions at their remediation site do not present a significant risk to human health or the environment.

This site received an NFR letter with no use restrictions or engineered barriers required.  Since the site clean-up, the property has been unoccupied and no longer has any hazardous substances on the premises.  Therefore, the previous contamination caused by past operations of the occupant represent an HREC for the site.

If you have questions about how Gabriel determines if an environmental condition is an HREC, contact Natalie Neuman, Group Leader Assessment Services, at 773-486-2123 or nneuman{at}gabenv.com.

Forest Preserves of Cook County seeking citizen scientists

FPCC logoForest Preserves of Cook County (FPCC) is seeking volunteers for several programs it runs to monitor plants or animal species of these natural reserves.

These ‘citizen scientists’ help collect data for the following programs:

FPCC uses this data to make decisions regarding new construction and development projects; focus management and restoration; and track whether things are expanding or declining for a plant or animal species.

“Monitoring over longer periods can give us an idea of whether the habitat is facing a downward trend, indicating more restoration or management work needs to be done, or show us positive results,” said Chip O’Leary, deputy director of resource management.

There are several upcoming volunteer training programs.  For more information on the different monitor programs and volunteer requirements, visit FPCC’s Volunteer Opportunities page.

Making spirits bright

christmas 2015 cja

Gabriel is proud to once again partner with Chicago Jesuit Academy to make their students’ Christmas celebration a little brighter and merrier.  As part of their last day of school before winter break, Gabriel donated gifts for each student specifically chosen with his interests in mind.  Gifts included science kits, drawing supplies, fiction books, LEGOs, non-fiction books, sports equipment, and games.  As you can tell from the pictures above, the young men were thrilled with their gifts.

Chicago Jesuit Academy (CJA) offers children with educational and economic needs access to a Catholic, college preparatory middle school education in the Jesuit tradition. In order to qualify for admission to CJA, each young man needs to have passed the fourth grade and qualify for the free or reduced lunch program or his family must be experiencing an extraordinary financial hardship. CJA seeks to serve students who could not otherwise afford a private education. CJA is a full-scholarship institution.

This year, Gabriel’s staff and matching gifts donated presents for 148 students at CJA, plus another 45 foster children with the Department of Children and Family Services (DCFS).

Merry Christmas to our friends at CJA and DCFS!

Thornton Reservoir fills for the first time

The Thornton Composite Reservoir is online and recently took on water for the first time while MWRD’s time-lapse camera was recording. A stormy Thanksgiving holiday resulted in 400 million gallons of combined sewage and stormwater flowing into the reservoir where the water level reached 17 feet. Though this is a lot of water, it’s only five percent of the reservoir’s 7.9 billion gallon capacity.

See the video from the MWRD’s Facebook page:

Gabriel toured the reservoir in June before it was completed as part of the MWRD’s flood management program.  See photos from our tour from this earlier blog post.
