On January 31, 2019 at 1 pm, the Yolo-Solano Air Quality Management District (YSAQMD) will be holding a public workshop as part of the rule amendment process. The rule project will focus on Rule 2.27 for boilers, with one of the main points of discussion being a reduction in NOx standards. Any facility with one or more boilers permitted by YSAQMD will be added automatically to the mailing list for this project. Any facilities without current YSAQMD boiler permits that would like to be added to the mailing list for this project can send their name and address to Paul Hensleigh, YSAQMD, at The public hearing for the regulation updates is expected to be held in April.

For any questions regarding existing Rule 2.27 for boilers, steam generators, and process heaters, please contact Denise Monahan, Trinity Consultants, at (916) 273-5154 or
