Common use of Weighing Clause in Contracts

Weighing. All mass inputs and outputs into and out of the process should be determined using weighing scales (or machines) that conform to the Canadian Weights and Measures Act (1985), or calculated by other suitable means (e.g. density, flow meter, metallurgical balance). All equipment is to be regularly inspected and calibrated. Sampling and Sample Preparation: Facilities should have documented sampling procedures that conform to provincial, national or international methodologies, or standards that are routinely practiced in the industry, and are equivalent to internationally known methodologies (e.g. ASTM, ISO). Analytical Testing: All analytical testing should conform to provincially, federally or internationally accepted analytical methods (e.g. ASTM (LECO)) or where applicable, methods that are routinely practiced by industry. Sampling and Testing Frequency: Each facility may use its own schedule and strategy for sampling and analytical testing, or a schedule and strategy in accordance with the requirements, if any, of the jurisdiction where they are located. Schedules and procedures should be documented and made available upon request. Continuous Emissions Monitoring: For measurement by a Continuous Emissions Monitoring System (CEMS), it is expected that the CEMS would be operated in accordance with Environment Canada’s EPS 1/PG/7 (Protocols and Performance Specifications for Continuous Monitoring of Gaseous Emissions from Thermal Power Generation) or any other method that complies with requirements under applicable legislation, permits or agreements with provincial regulatory authorities. Mass Balance: Sulphur mass balance calculations should be conducted, at a minimum, on a monthly basis, and records of the results kept. Particulate Matter Measurement: Particulate matter emissions measurement could be done by source testing, Continuous Emissions Monitoring (CEM) or a combination of the two. Where source testing and CEM is not operationally feasible, other methodologies, as identified in Annex 1, may be used. Methodology: Any of the following standard methods should be used for source testing: • Environment Canada’s EPS/1/RM/8 (Standard Reference Method for Source Testing: Measurement of Releases of Particulate Matter from Stationary Sources); • Environment Canada's EPS 1/RM/55 (Reference Method for Source Testing: Measurement of Releases of Fine Particulate Matter from Stationary Sources); • US EPA Method 5: Determination of Particulate Emissions from Stationary Sources • Ontario Source Testing Code, Method 5: Determination of Particulate Emissions from Stationary Sources; • Xxxxxxx Xxxxx Sampling Code; • Any other method that complies with requirements under applicable legislation, permits or agreements with provincial regulatory authorities. For measurement by a Continuous Emissions Monitoring System (CEMS), it is expected that the CEMS would have, at a minimum: • Correlation by source testing on a regular basis according to Environment Canada’s EPS 1/RM/8, or any other equivalent method. Frequency: Source testing should be performed, at a minimum, according to the frequency specified in Table 1 of Annex 1.
