Summary:

Rule 5-6, Standards of Performance for Regulated Medical Waste Incinerators (Article 6 of 9VAC5-50) was originally adopted in response to a directive from the General Assembly in 1992 (Chapters 773, 774, and 751). Since Article 6 was adopted, a more restrictive U.S. Environmental Protection Agency new source performance standard covering the same type of sources was promulgated and adopted by Virginia. Because there is no longer a need for the original, less-restrictive Virginia regulation, the 2013 General Assembly enacted Chapter 632, which removes the provisions relevant to air quality from Chapters 773, 774, and 751. Article 6 of 9VAC5-50 is being repealed because its underlying state requirement has been removed.
