This proposal is for a new Environmental Compliance Approval (industrial sewage) for one mobile sewage works for the treatment of process water, stored water, surface water, or groundwater impacted with petroleum hydrocarbons, gasoline, diesel fuel, oil, volatile organic contaminants, polyaromatic hydrocarbons, per- or polyfluoroalkyl substances (PFAS), halogenated and non-halogenated solvents, surfactants, as well as other organic and inorganic contaminants.

Each mobile unit is capable of treating surface water or ground water at a rate of 100 litres per minute (more than one of these systems may be used simultaneously on the same site) and is comprised of one settling/separation tank, one or more optional oil/water separator(s), one or more optional bag filter(s), one or more optional organo clay vessel(s), one or more optional granular activated carbon vessel(s) connected in series and one or more activated alumina filters and one or more PFAS filters, all housed in a secured mobile trailer or shipping container.

Treated effluent from the works meeting Provincial Water Quality Objectives, Ontario Drinking Water Standards and/or Full Depth Generic Site Condition Standards in a Potable Ground Water Condition (soil, ground water and sediment standards for use under part XV.1 of the Environmental Protection Act) is to be disposed through discharge onto the ground, surface water body, controlled structure, sanitary sewer or storm sewer (where allowed by municipal by-laws) depending on the site location.
