General Announcements

General Announcement for AQ Permit Holders
Effective January 16, 2021, all air quality applications, Permits, Requests for Determinations and initial Asbestos Notifications will be subject to new and/or increased fees. The Saturday, January 16, 2021 effective date is the result of a three-year regulatory process and will be finalized upon publication in the Pennsylvania Bulletin on that date. These fees were last updated in January 2005 and will address the long-term disparity between revenue and expenditures in DEP's Air Quality Program. Any air quality application, Requests for Determination or initial Asbestos Notification received on or after January 16, 2021 must be accompanied by the appropriate new or updated fee. The final rulemaking also includes an Annual Maintenance Fee (replacing the annual administrative fee) due each year for Natural Minor, Synthetic Minor and TV permitted facilities. This maintenance fee does not replace the annual TV emission fees due September 1 by most TV facilities. The Annual Maintenance Fees for calendar year 2021 are due on or before March 17, 2021, 60 days after the January 16, 2021 final rulemaking publication. Subsequent maintenance fees are due annually no later than December 31 for the next calendar year. The maintenance fees are $8,000 for TV Permitted Facilities, $4,000 for Synthetic Minor Permitted facilities and $2,000 for Natural Minor Permitted facilities. Information regarding the Annual Maintenance fee, including a transmittal fee form to be submitted with the fee, will be coming in separate website and email notifications in the near future. The new air quality regulations can be found on the Pennsylvania Bulletin website.

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 here.

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 following report.
