Join Gabriel for the Illinois Solar Tour


Gabriel is proud to be a host site for this year’s Illinois Solar Tour on Saturday, October 4th.  This free, self-guided tour will be held from 10:00am – 2:00pm.

Stop by our Chicago headquarters to view our 162 solar panels, geothermal systems, and rain barrel system, as well as learn about the economics of our solar energy system.

The Illinois Solar Tour gives you the opportunity to:

  • Visit multiple renewable energy installations in your neighborhood
  •  See and learn about:

– solar electric (PV)
– solar thermal (hot water and space heating)
– small wind (horizontal and vertical)
– geothermal
– and passive solar design

  • Speak with knowledgeable professionals and homeowners
  • Meet like-minded neighbors
  • Hear the owners’ stories about why they chose to install renewable energy, their experiences with it, and how this decision has enhanced their lives.


This is a self-guided tour, so you get to choose which homes and businesses (host sites) to visit, how many, and when, within the 10:00am – 2:00pm time span.  Host sites have been chosen within each geographic region for their proximity to others and to facilitate the option of visiting all of them. Each host site tour will take anywhere from 15 – 45 minutes, depending on the size of the site and the number of renewable energy installations.

2014 Governor’s Sustainability Award Finalist

ISTClogoGabriel is pleased to announce that we have been named as a Finalist for the 2014 Governor’s Sustainability Award.  The Governor’s Award is given to companies and organizations that implement techniques or technologies that reduce or eliminate pollutants, toxicity and other environmental impacts, including the amount of and/or toxicity of pollutants that would have otherwise been released into the environment.

Gabriel made the Finalist list due to our recent solar panel expansion as well as our use of electric cars and hybrid cars.  We increased our solar panel array from 36 PV panels to 162 panels, for a total capacity of 42,000 watts (visit our Picasa photo album of the expansion).  Our fleet currently features three Prius hybrids, a Nissan Leaf (all electric), Chevy Volt (electric-gas hybrid), and Ford C-Max (electric-gas hybrid).

Winners will be announced on October 23rd, 2014, so stay tuned for another announcement next month!

UIC Offers Workshop on “PCBs and Their Impact on Illinois”


On September 17, 2014, University of Illinois at Chicago will host a workshop entitled “PCBs and Their Impact on Illinois.”  This presentation will include expert discussions on:

(1) Background on PCBs and their impact on Illinois

(2) Managing PCBs with the use of landfills

(3) Other means of managing PCBs

(4) PCB clean-up success stories


The industrial use of synthetic chemicals known as PCBs (polychlorinated biphenyls) was banned during the 1970s, but they have proven to be a persistent pollutant, requiring new technological approaches to destroy or safely isolate them from the environment.

This seminar will be held at UIC’s Student Center East and online. For additional details, and to register for the workshop, please visit: http://www.istc.illinois.edu/info/ pcbworkshop.cfm

EPA Set to Issue Final Rule for AAI Changes

EPA is finishing their review process prior to issuing the Final Rule EPA amending the All Appropriate Inquiry (AAI) regulations to remove reference to ASTM E1527-05 and replace with E1527-13.  This ASTM Phase I Environmental Site Assessment standard was updated in November 2013 and confirmed by EPA to be compliant with the AAI rule in December 2013.

EPA received five comments to their proposed rule in July 2014, four of which were positive and one of which was negative.  EPA will address the negative comment in the Final Rule’s preamble and explain its reasoning for why it disagrees with the comment.

EPA will also clarify in its preamble that any Phase I’s completed to the ASTM E1527-05 standard between November 1, 2005 and the effective date of the Final Rule will still be considered as compliant with the AAI regulations.

EPA has stated that it intends to make the effective date one year after the Final Rule is published, which is expected to occur in late September/early October.  They decided that an earlier effective date may be burdensome to some entities who are still transitioning to the new ASTM standard.  Any Phase I’s completed for federal Brownfields grants, however, must be completed to the E1527-13 standard effective immediately, upon the date the Final Rule is published.

For more information on the proposed Rule and to access the comments submitted, visit the EPA’s Proposed Rule for Standards and Regulations of All Appropriate Inquiries webpage.
