The purpose of today's hearing is to give the public an opportunity to comment on the proposed amendments to Regulation .01 Applicability and Exemptions under COMAR 26.11.35 Control of Volatile Organic Compounds from Adhesives and Sealants.

Background

COMAR 26.11.35 Control of Volatile Organic Compounds from Adhesives and Sealants was adopted on January 11, 2008. The regulations affect a large number of sources and materials and provide significant reductions of VOCs. Due to the large scale impact of the regulations, the Department adopted the standards after an extensive analysis and outreach effort in 2007. The

12 purpose was to give affected sources and manufact urers sufficient time to test new materials and make process changes to meet the new standards.

In January 2008, the EPDM Roofing Association raised concerns about the VOC limitations for roofing adhesives when applied at lower temperatures. EPDM recommended a seasonal phase-in to the VOC regulation, requiri ng the use of VOC-compliant adhesives during the warmer “ozone season” months while continuing to allow higher VOC adhesives during the colder months for a period of time necessary to develop a new low-VOC technology that could be effective on a year-round basis. The Department requested the OTC to review these concerns with the intention of reaching consensus among states as to how to address this issue. The OTC did not make changes to the model rule after its review, but rather left it up to the states to decide on how to respond to the request. A number of states have decided to give non-ozone season exemption in the initial years of implementation. The Department met with manufacturers, installers and association representatives regarding additional time in the non-ozone season period to better train and modify practices for the use of new materials at lower temperatures. As a result of discussions and in order to provide more time for training, the Department agreed to provide a limited exemption for the non-ozone period in the initial phase of implementing the regulation.

Summary of Amendments

COMAR 26.11.35.01 Applicability and Exemptions is being amended to limit the applicability of VOC standards for single-ply roof membrane installation and repair adhesives, single-ply roof membrane sealants and single-ply roof membrane adhesive primers according to the following schedule:
