Proposals Recently Finalized
Final Industrial Cleaning Solvents Rule
The Department published its final Industrial Cleaning Solvents rule in the Pennsylvania Bulletin (48 Pa.B. 4814, August 11, 2018) 25 Pa. Code Section 129.63a (relating to control of VOC emissions from industrial cleaning solvents) effective August 11, 2018. It was submitted to EPA as a requested
SIP revision on August 13, 2018.
Suspension of Enforcement of Summertime Gasoline Volatility
The Department recently announced that it was suspending enforcement of the gasoline volatility requirements in 25 Pa. Code Chapter 126, Subchapter C (relating to gasoline volatility requirements) for the Pittsburgh-Beaver Valley area effective May 1, 2018, through September 15, 2018.

Marcellus Shale Long-Term Air Monitoring Project Report
The Department of Environmental Protection undertook a project to examine the impacts from air emissions from unconventional gas production within Washington County. Data was collected over a one-year period in 2012-2013 and results were subjected to a series of analyses conducted by DEP, DOH and the federal Agency for Toxic Substances and Disease Registry (ATSDR). Air quality measurements were collected from 5 Washington County sites, and an additional comparison was performed using data from an air monitoring station in Adams County. Air quality was monitored for ground-level ozone, particulate matter, carbon monoxide, nitrogen oxides, hydrogen sulfide and methane. Additionally, the air was tested for over 60 toxic volatile organic compounds (VOCs). Continuous meteorological data was also collected.
The air data was compared to National Ambient Air Quality Standards (NAAQS), ATSDR public health comparison values, Air Quality Index (AQI) indicators, and background values found in Pennsylvania. The data was also subjected to a screening-level risk quantification for hazardous air pollutants. The report from ATSDR can be found
Analysis of Data: Long-Term Particulate Matter Monitoring (Bath Borough, PA)
The department initiated continuous, 24-hour ambient air monitoring for total suspended particulate (TSP), sulfate and select metals at a location near the Keystone Cement Company production facility in East Allen Township, Northampton County, PA in 1995. Sampling was initiated to monitor the facility's particulate emissions in the ambient air and to evaluate the potential health effects on the community. Upon completion of the sampling in 2015, the data was analyzed and compared to health-based screening values. The findings from the analysis can be found in the
Pennsylvania State Clean Diesel Grant Program:
DEP is accepting applications for the FY2017 PA State Clean Diesel Grant from May 19, 2018, to July 6, 2018. Go to
DEP's Driving PA Forward website Program Guidelines, Application Instructions, and a link to the online application system.
DEP 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, used 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.
DEP awarded $75,900 to AKS Inc. under Round 2 of the FY2014-2016 PA State Clean Diesel Grant Program. AKS Inc., located in Etna, PA, used the funds to replace four older diesel school buses with four 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.
DEP awarded $21,723.50 to High Point Baptist Chapel under Round 2 of the FY2014-2016 PA State Clean Diesel Grant Program. High Point Baptist Chapel, located in Geigertown, PA, used the funds to replace one older diesel school bus with one new diesel school bus. 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.
DEP awarded $200,000 to Shultz Transportation under Round 2 of the FY2014-2016 PA State Clean Diesel Grant Program. Shultz Transportation used the funds to replace 10 older diesel school buses with 10 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.
