On March 7, 2017, Scott W. Nowicki, TTI’s Director of Inspection Service, attended the quarterly meeting of the Pennsylvania Storage Tank Advisory Committee (STAC) at the Rachel Carson State Office Building in Harrisburg.  Mr. Nowicki is the appointed representative of the Pennsylvania Chemical Industry Council (PCIC) and the regulated community, and one of 15 voting members on the STAC, discussing storage tank issues and providing technical advice to the Department.

Of particular interest to PADEP-regulated storage tank owners in Pennsylvania was STAC’s approval of the latest iteration of the draft proposed storage tank regulations (Chapter 245, Administration of the Storage Tank and Spill Prevention Program).  From here the draft regulation will be under review by the Environmental Quality Board, which will allow for public review and comment.  Some notable proposed changes include a new cathodic protection testing form for routine CP inspections, a new 3-year in-service inspection interval for vaulted aboveground storage tanks (previously 10-year), and a new 5-year in-service inspection interval for aboveground storage tanks less than 21,000 gallons (also previously 10-year).  Once approved, these new regulations are expected to become effective in mid-2018.

Also announced was the new Land Recycling Program Vapor Intrusion Guidance document, published November 19, 2016, has become effective January 18, 2017.  This document is available for download from the PADEP’s website. (
