The facility level emission inventory starts with a detailed knowledge of the processes and operations which are typical of the industry and their specific implementation within the facility, and experience in developing estimates of emissions for these or similar processes. We have developed facility level emission inventories for:

petrochemical facilities	Suncor Refinery, Sarnia; Petro-Canada Lubricants Plant, Mississauga; Petro-Canada Refinery, Oakville; Bulk Storage Terminals in Toronto, London and Sarnia
primary smelters	Glencore (Xstrata, Falconbridge, Noranda Horne, Gaspe, and CEZ); Teck (Cominco) Lead Smelter at Trail
integrated steel plants	Essar Steel (Algoma, Sault Ste Marie)
auto assembly plants	Honda of Canada Manufacturing, Alliston; GM at Ste. Therese, Oshawa and St. Catharines
cement plants	St. Mary’s, Bowmanville; Lafarge, Bath
chemical plants	Mancuso, Niagara Falls
secondary lead smelters	Tonolli, Mississauga
energy	OPG at Nanticoke, LNG facility, Thorold

The emission estimates developed need to be proven to the regulatory agency, which can involve detailed process simulation, use of sampling data, or model estimation of emissions, such as the CAMM process in Ontario. We have carried out several CAMM studies on behalf of clients, and have been involved in extensive discussions to improve the process.
