Data Requirements Rule — List of SO2 Sources Identified for Air Quality Characterizations

On January 15, the department submitted a list to the USEPA of large Sulfur Dioxide (SO2) emitting sources in the Commonwealth which will undergo "air quality characterization" as required under the final Data Requirements Rule for the 2010 1-Hour SO2 Primary National Ambient Air Quality Standard.

Recent Department Comments to EPA Proposals:

Baseline Tunkhannock Crystalline Silica Monitoring project

In response to requests for baseline ambient air monitoring in Tunkhannock Township, Wyoming County, the Department performed a short-term background air monitoring project to measure ambient crystalline silica concentrations. Crystalline silica was measured and reported as particulate matter, 4 microns (PM4). The sampling project also involved collecting baseline fine particulate matter including PM2.5, PM10 and PM4 ambient crystalline silica samples. An analysis of the results of the sampling determined the baseline levels of ambient crystalline silica concentrations in the monitoring area.

Grant Availability

Pennsylvania State Clean Diesel Grant Program:

The PA State Clean Diesel Grant Program is re-opening to accept applications. Applications will be accepted from Apr. 8, 2017 through May 12, 2017. The grant announcement is published in the Pennsylvania Bulletin of April 8, 2017. The goal of the grant program is to improve Pennsylvania's air quality by decreasing emissions from diesel-powered vehicles and equipment. The available funding for this round is $396,904. The grant guidelines and application are available through the links below. The application is a 'fill-in-the-blank' form. A plain text application that can be printed and filled out by hand is available upon request. See guidelines for contact information. A webinar was recorded during the first round of funding this year. Please see the links below to view the recorded webinar.

GRANTS AWARDED

DEP has awarded $122,920 to the Berks County Intermediate Unit (BCIU) under Round 1 of the FY2014-2016 PA State Clean Diesel Grant Program. BCIU, located in Reading, PA, will use the funds to replace six older diesel school buses with six new diesel school buses. These replacements will result in improved air quality in the areas of operation and reduce exposure to diesel emissions for the operators and occupants of these buses.
