ACCAN BreathCams for Metalico Pittsburgh and Riverside Concrete & Supply

Metalico Pittsburgh on Neville Island


Allegheny County Clean Air Now (ACCAN) was founded to give a voice to those harmed by the pollution from the DTE Shenango Coke Works on Neville Island. (See for a history of  ACCAN’s effort to get better regulation of Shenango, which finally closed in January, 2016).


With Shenango gone, ACCAN is focusing on other polluters in the Neville Island airshed.  In 2017, ACCAN became aware that Emsworth residents were being bombarded with pollution and explosions by Metalico Pittsburgh, a metal recycling and shredding industry across the Ohio River on Neville Island.   As in the case of Shenango, an ACCAN BreatheCam was deployed in 2018 to provide 24/7 documentation of the industrial pollution from Metalico that harms our health and environment.   From 2018 to May, 2024, ACCAN, using the BreatheCam and reports from Emsworth residents, has documented more than 700 complaints that can be seen in the blog on this website.

Riverside Concrete & Supply in Coraopolis


In June 2023, ACCAN first heard about the problem with Riverside Concrete & Supply (a division of the Bryan Materials Group) from Coraopolis residents who live across the street from this concrete batch plant.  Concrete batch plants mix a combination of materials, including cement, to make concrete.  Riverside states that the materials they mix are sand, gravel, limestone and cement.  The mixture is then loaded into cement trucks.  

The neighborhood is subjected to  dust and other emissions from Riverside.  The types of emissions from the plant include cement dust, dust from the mixture of materials (particularly when it gets loaded into cement trucks), road dust, dust from aggregate piles, dust from the operation of the conveyor belt, emissions from onsite internal combustion engines and diesel exhaust from cement trucks that idle for hours, beginning as early as 5:00 a.m. every day.

This type of plant should not be located in a densely populated neighborhood that includes homes and a 40 unit Section 8 apartment complex that are directly across the street from the plant and a 200-unit senior citizen highrise that is a block away..

Residents have been complaining for years about Riverside and in early 2022 they started to increase their complaints to the Allegheny County Health Department.  Health Department inspectors did respond to the residents and started to have conversations with the company; however, nothing changed and the residents stopped hearing from the inspectors.  After the residents contacted ACCAN in June, 2023, we began to work with them on ways to get more of a response from the Health Department and better regulation of the plant. Currently the plant is not required to have an air quality permit from the Health Department.  Residents continue to submit complaints and when ACCAN members can get to the site, we also document pollution events and submit our own complaints.  Just recently, with the help of our partner, CMU’s CREATE Lab, we installed an ACCAN BreatheCam to watch Riverside 24/7. We use video from this BreatheCam to document pollution events and submit complaints to the Health Department. The camera video from this BreatheCam can be viewed on this website along with a complaint blog for Riverside which, as of May 2024, included 245 complaints.
