Air Quality Concerns
Dust Controls
Per the Temporary Use - Rock Crushing By-law, OBD Developments Inc. shall implement the following measures to control fugitive dust:
- The crusher shall be equipped with a water spray system.
- The water spray system shall be operated at all times while the crusher is in operation, except when precipitation is sufficient to offset the operations of the water spray system.
- The crusher shall not be operated when water is unavailable.
- The crusher shall not be operated when temperatures are below 4 degrees Celsius to ensure water spray does not freeze.
- Crusher shall not exceed 1000 tonnes per day.
- Crushing activities shall be avoided when wind is blowing towards the homes.
- The site manager and onsite personnel shall report any observations of fugitive dust blowing towards the residents adjacent to the site.
Air Quality Monitoring
Air quality monitoring program will be in place prior to and for the duration of operations at the site, which must include the following parameters:
- The program will consist of two e-samplers equipped with gravimetric filters.
- The equipment shall collect continuous data on airborne PM10 concentrations as a surrogate for other particle fractions and potential levels of crystalline silica.
- Calibration and maintenance as per manufacturers instructions.
- Locations will be determined through consultation.
- The e-samplers will be connected to RWDIs data acquisition system.
- This system shall be configured to send alerts and reports to relevant users and stakeholders. Alerts will be sent if:
- If measured concentrations of PM10 exceed 50% of the Ontario Ambient Air Quality Criteria, on a 24 hour rolling average, while operations are underway at the site, a notification shall be sent to the site manager to increase dust control measures.
- If measured concentration of PM10 exceed 100% of the Ontario Ambient Air Quality Criteria, on a 24 rolling average, while operations are underway at the site, operations shall cease immediately.
- If operations are not underway at the time, this shall be recorded and an attempt shall be made to identify the source or the particulate (example: smoke, other construction activities in the area).
- Summary memo reports shall be produced and filed monthly.
If you have concerns that OBD Developments Inc. is not abiding by the above noted sections please contact the Site Supervisor and By-law Enforcement.
