Proposals Open for Comment
Interstate Pollution Transport Reduction; Proposed 2017 Ozone Season Nitrogen Oxide Emission Limits for Nonelectric Generating Units
The Department of Environmental Protection is providing notice and an opportunity for comment concerning the proposed Nonelectric Generating Unit (non-EGU) 2017 Ozone Season Nitrogen Oxide (NOx) emission limitations established in accordance with 25 Pa. Code §145.8(d) (relating to transition to CAIR NOx trading programs).
The 15-day public comment period will end on March 27, 2017.
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.
Pennsylvania State Clean Diesel Grant Program:
The PA State Clean Diesel Grant Program is now accepting applications, from Nov. 12, 2016 through Dec. 28, 2016. The grant announcement was published in the Pennsylvania Bulletin on Nov. 12, 2016. 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 year is $519,824. 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. Please ensure that you register for the Nov. 30, 2016, webinar, if interested.
