The Department of Environmental Protection published notice of final technical guidance on Land Recycling Program Vapor Intrusion Into Buildings From Groundwater and Soil under Act 2 in the November 19 PA Bulletin. (DEP ID: 261-0300-101)
The Land Recycling Program Vapor Intrusion (VI) Guidance has been substantially revised to update scientific deficiencies of the current guidance. Screening values and the way they are calculated have been updated and there are multiple clarifications that have been made to language, definitions and procedures.
Revising the guidance helps avoid confusion for remediators and regional office staff about how to address the vapor intrusion pathway under the Statewide health standard and the site-specific standard.
The Department solicited comments on the draft VI guidance for 30 days, beginning on July 25, 2015. During the comment period, 97 comments were received from 8 different organizations.

The guidance will be effective January 18, 2017.
