Clarification for RFI BE 2019-2119-111
Enquiry
We request clarification on the response to RFI BE 2019-2119-111 which states that “The OGS design shall include the total pavement area”. The total pavement area for the proposed interchange within the study area (including QEW) is approximately 200,000 m2. The new pavement area accounts for approximately 20,000 m2. The design presented in the DBRR provides treatment through OGS units in combination with CB shields for approximately 11,000 m2 of pavement. The industry standard is to provide water quality treatment for all new pavement in order to meet the MECP requirements. Please clarify the response which indicates the OGS design shall include “total pavement area”, since if all of the pavement area (existing and proposed) within the study area is included there would be a significant increase in the number of OGS units required to provide water quality treatment. Does this statement indicate that the total pavement area (i.e. approximately 200,000 m2) should be considered for treatment, or does the statement refer to the total contributing drainage area to each OGS (as identified in the DBRR) should be considered in the design for water quality treatment of the additional pavement?
