RJS Logo 06Oct2011

 James Slater, Principal of RJS Environmental Services (RJS), has over 30 years of experience as a professional biologist, and specializes in Stage 1 Preliminary Environmental Site Investigations (PSI’s). Since 1998, RJS has conducted more than 300 PSI’s as an independent sub-consultant in Metro Vancouver.  These reports have been accepted by major lending institutions in Metro Vancouver and Toronto.  

RJS now operates as a sole proprietorship, and is fully covered for Commercial General Liability, as well as Errors and Omissions (Professional Liability).

A Stage I Preliminary Site Investigation (PSI) is the first step in evaluating the likelihood of soil or groundwater contamination to be present at a site from current and historical uses.

Stage 1 PSI's are also referred to as Phase 1 Environmental Site Assessments, or Phase 1 ESA's.

Identifying whether potential environmental liabilities exist, at an early stage, can circumvent many unforeseen obstacles which may affect the value of the property A clean site is a good site, both for the environment and the interested parties.

  A Stage 1 is a non-intrusive investigation that does not require physical soil or groundwater sampling or analysis. The scope of work for a Stage 1 report includes an inspection and photographic documentation of the site and adjacent properties, a review of land use and permitting records, analysis of historical air photos, an historical directory search, and interviews with knowledgeable sources. A search of the Contaminated Sites Registry (CSR) is also conducted to identify potentially contaminated sites within 150 m of the subject property.

A Stage 1 provides due diligence for property vendors, prospective purchasers, and lending institutions, but may also be used to collect indispensable baseline environmental information about the subject property for future uses and activities.

RJS Stage 1 reports are conducted in accordance with the Environmental Management Act, Contaminated Sites Regulation, the Canadian Standards Association (CSA) Standard Z768-01, and other applicable legislation enacted by the Province of British Columbia.

Stage 1 PSI's also identify the proximity the nearest watercourses or water bodies, and whether they are fish-bearing or fish habitat. The B.C. Contaminated Sites Regulation (CSR) soil and groundwater standards for protection of aquatic life (AW) may be applicable at distances of less than  500 m.   

A Stage 1 report usually takes two weeks (10 working days) to complete.  However, an Interim Report summarizing the findings of the PSI and its conclusions can be made available within one week (5 working days), if necessary, at no extra cost. The Interim Report is usually sufficient for conditional approval by the lending institution.
