Summary of the South Coast Air Quality Management District Rules
The state of California has been divided into 35 air districts, each with their own requirements. District borders are established by the state legislature; many follow county borders. If there is a question concerning which district a particular location is part of, detailed border descriptions are available at the district website.
Please be advised that not all districts have emissions requirements that affect the types or sizes of product that Raypak manufactures. Furthermore, certain districts exempt propane-fired units from regulation, and others do not. It is important to be aware of current requirements in each district.
The California Air Resources Board (ARB) maintains a site with information on each district and their requirements. See the links below.

|BTUH||Year Manufacturer||Effective Date||NOx Standard|
|75,000-400,000|| ||Exempt|| |
|400,001-1,000,000||All||January 1, 2006||Less than 30 ppm|
|1,000,001-2,000,000||1992 or later||January 1, 2006|| |
Units operating in the District, must be retrofitted or replaced to comply with the new NOx emission standards by the stated effective dates if the unit is one that consumes over 9,000 therms per year. This equals 900 hours of operation per year for a 1,000,000 BTUH boiler firing at full rate. Low usage units, such as some heating boilers and seasonal use pool heaters, are exempt from the retrofit/replacement requirement.
Sale of products moving forward Product manufactured before 1/1/2010 (or 1/1/2012 for under 400K) can continue to be sold in the district until 12/31/2010 (or 12/31/2012 for under 400K) (See Rule 1146.2 Sections (c)(11) and (c)(12) respectively. Hi Delta, MVB and XTherm product will ALL meet these new requirements, we are ONLY talking about Raytherm product (particularly Series V Lo NOx) which would have to be sold and installed by 12/31/2012.
