Effects of consultation

Comments provided were considered. The current amended sewage works approval includes stormwater management works only. The comments received were also related to other media and the relevant ministry staff have been advised of those comments. The comments that were related to stormwater management works were addressed in the subject approval.

For some comments related to the application form, ministry has obtained clarification from the applicants. Responding to some comments, the applicants have informed that they are working with City of Hamilton to resolve comments. The current sewage works approval requires that the stormwater discharge from the pond meet the applicable effluent criteria prior to discharge. Additionally, the owners are required to undertake monitoring, reporting and contingency measures in order to avoid any impacts to the receiving environment. A ministry approval does not relieve any person of any obligation to comply with any provision of any applicable statute, regulation or other legal requirement.

A comment was received about stormwater management pond dredging and maintenance. The ECA conditions require the owners to clean and maintain the works to prevent excess build-up of sediment and vegetation.

A comment was received to consider controlled discharge from the stormwater management pond. The previous approval required the owners to operation the pond in a normally open condition. This, however, has been revised and the current approval requires the owners to operate the pond in a normally closed condition. Stormwater discharge from the pond can be released upon a confirmation that the effluent quality has met the effluent requirements as per current approval.

If the appellate body grants leave, the appeal itself will follow.

Proposal details

This application is for an amendment to existing Industrial Sewage ECA No. 5400-7DSSHU (May 1, 2008) that permits the stormwater management facility and leachate collection and disposal facility to service the Stoney Creek Regional Facility [currently identified as the Newalta Stoney Creek Landfill in ECA No. 5400-7DSSHU (formerly known as Taro East Landfill)] located at 65 Green Mountain Road West in the City of Hamilton.

The ECA permits the stormwater management facility to service a total of 34 hectares drainage area of Phase1 of Newalta Stoney Creek Landfill designed to provide quantity and quality control of stormwater runoff from storm events with up to 1:100 year return frequency. The ECA permits operation of a leachate impacted groundwater and stormwater collection system, including a leachate collection pond and leachate equalization lagoon.

This Amendment application includes a name change and a new Leachate Treatment System (LTS) to replace the existing treatment system. The primary purpose and function of the LTS is to remove odour from the leachate collected through the leachate collection system prior to discharge to the sanitary sewer network, while adhering to requirements of the City of Hamilton Sewer By-Law No. 14-090 and City-issued Sewer Discharge Permits.

This application includes an updated proposed Stormwater Management (SWM) Plan to achieve the required water quality and quantity controls for the continued operation of the Site.

The site receives a maximum of 8,000 tonnes per day, for the disposal of solid, non-hazardous commercial, institutional, and industrial waste including petroleum contaminated soils. The maximum volume of waste and cover material, excluding final cover, which may be disposed of at the Stoney Creek Regional Facility is 10,180,000 cubic metres and will serve the Province of Ontario. The facility accepts waste Monday through Friday between the hours of 7:00 a.m. and 5:00 p.m. and is closed weekends and statutory holidays.
