Many facilities in Ontario can now register with a new system by the Ministry of Environment, Conservation and Parks (MOECP) called the Environmental Activity and Sector Registry (EASR). This registry was devised by the MOECP as part of their modernization of approvals to allow lower-risk facilities to self-register, rather than go through the often-time-consuming process of review and approval by Ministry engineers. An important part of this registration is the noise study, or Acoustic Assessment Report (AAR), which evaluates the noise impact against the sound level limits and includes a description of any required noise controls. Unlike the Environmental Compliance Approval (ECA) process, a noise study needs to be dated, signed and sealed by a licensed engineering practitioner (P.Eng.). Aercoustics has many Professional Engineers on staff who are familiar with the detailed new requirements from the O.Reg. 1/17 legislation, so you can be confident that if your facility gets audited, you won’t have to worry. We have supported a large number of facilities through the EASR process, such as Hydro One, food distribution centres, and peak-shaving generator installations.
