The REMI model was used for conducting a socioeconomic analysis by the South Coast Air Quality Management District that assessed the impacts of Proposed Amended Rule 1143-Consumer Paint Thinners and Multi-purpose Solvents. The proposed rule amendments would reduce volatile organic compounds emissions by 3.81 tons per day by 2012, which would contribute towards attaining the federal PM 2.5 and ozone standards in 2014 and 2024, respectively. The analysis included two scenarios to bracket a range of potential impacts, which were the cost of PAR 1143 incurred either by consumers as price increased or by manufacturers who would have to reformulate their products to meet the requirement for PAR 1143. The first scenario determined that consumers might experience an increase in the product price of $3-$42 per gallon, with the majority of price increases expected to be $11 per gallon. The second scenario revealed that $3.5 million would be borne by local manufacturers, on average, from 2011 to 2013, with the remainder of the $13.8 million average annual compliance cost would be paid by manufacturers outside the Air Quality Management District.
