  34. Approval Compliance Evaluations

  35. Approval Compliance Evaluation (ACE) • Purpose • Evaluate COA compliance • Answer COA questions • Piloted in May 2004 • Standardized procedure (SOP) • Cooperative effort developed by DHW & DELG • To be completed by Public Health Inspector and Drinking Water Systems Engineer • To be conducted for all 67 municipalities in 2004 • Conducted in both English and French

  36. Approval Compliance Evaluation (ACE) • Comprised of interview, records review and facilities inspection • Completed by 1 Engineer and 1 PHI (typically) • DELG Engineers are “Designated Inspectors” under the Clean Environment and Clean Water Act • Checklist arranged so that “yes” indicates compliance with COA • Yes indicates that minimum COA requirements are being met (based on interview responses, records provided and facilities visited) • Exit Meeting Purpose: review findings and allow for comments and discussion • RWPO, municipal officials also invited to attend exit meeting

  37. Statistics… • 67 municipal systems • 185 wells & 22 surface water sources • 362,000 people serviced by municipal DW • Per capita consumption: 165/2320/680 L/person/day • Prevalent Water quality issues – microbiological, turbidity, hardness, THMs, Fe, Mn, colour, corrosivity, NO3/NO2 • Disinfection • 54 with chlorine residual; 10 with standby • 1 ozone; 3 UV disinfection • Certification level achievement ~50%

  40. Questions

  41. Contaminated Sites Program Remediation Branch - DELG

  42. Acts and Regulations Governing Contaminated Sites Management • Clean Environment Act, RSNB, 1973,c.C6 – paragraph 5(1)(g) • Petroleum Product Storage and Handling Regulation – Clean Environment Act (N.B. Reg. 87-97) • Subsection 10(4) of the Water Quality Regulation – Clean Environment Act http://www.gnb.ca/0009/index-e.asp

  43. Policies/Protocols Governing Contaminated Sites Management • Guideline for the Management of Contaminated Sites – Version 2, November, 2003 • Atlantic RBCA User Guidance – Version 2, October 2003 • Other Departmental Policies such as the Limited Remedial Action Reference Documentation for Site Professionals, Compliance and Enforcement Policy, Application of Atlantic RBCA in Wellfields http://www.gnb.ca/0009/index-e.asp

  44. Evolution of CSM in New Brunswick • 1987 - Petroleum Product storage and Handling Regulation (8000 tanks removed, replaced, inspected) • 1992 – Guidelines for the Assessment and Remediation of Contaminated Sites (Generic Criteria – 50 sites closed prior to 1999) • 1997 – PIRI Committee formed to explore development of Risk Based Clean-up Criteria • 1998 – Remediation database created • 1999 – Atlantic – wide technical tool RBCA Version 1 and NB Guideline for the Management of Contaminated Sites implemented (640 sites closed since 1999). This allows for closure at Tiers I-III.

  45. Risk Assessment RECEPTOR EXPOSURE RISK HAZARD

  46. Atlantic RBCA (Risk-Based Corrective Action) • Atlantic RBCA model based upon the ASTM Standard. • Acceptable incremental risk from contamination based upon an increase of risk of negative effects to human health of 1 in 100,000. • Source (Contaminants) classified as carcinogen or non-carcinogens and also by their behavior in the environment (how they leach from soil, how they dissolve, how they vaporize • Receptors classified as commercial or residential, by age of receptors and by duration of exposure. • Exposure classified as the active pathways between the source and the receptor (i.e. indoor air vapors from soil and groundwater, outdoor air vapors from soil and groundwater, dermal contact with soil, soil or groundwater consumption.) • Corrective action involves removal of part or all of the source, receptors and exposures to reduce risk to an acceptable level.

  47. Atlantic RBCA (Risk-Based Corrective Action) • Three Tiers of risk assessment available. • At Tier I, compare site results for petroleum hydrocarbons in soils and in groundwater to look-up tables developed for typical Atlantic Canadian conditions based upon contaminant type, water supply land use and aquifer type. • At Tier II, compare the site results to site-specific clean-up numbers generated by the Atlantic RBCA model. Input to the model can be varied from the typical Atlantic conditions to reproduce site specific conditions. The model has only been validated for petroleum hydrocarbons. • At Tier III, evaluate risk by use of other computer models, monitoring data, soil gas, or air quality data. Risk assessment of non-petroleum contaminants and ecological risk assessment occurs at Tier III. • Risk assessment costs typically increase at each Tier but may reduce costs of corrective action.

  48. Technical and Management Tools in New Brunswick

  49. Roles in the Management Process • Responsible Party defined as per Acts and Regulations – usually the person who caused or contributed to contamination. Sale/transfer of land does not usually affect who is the Responsible Party. • Site Professional defined as someone possessing the qualifications of a professional engineer or geoscientist as defined by APEGNB. The Site Professional works on behalf of the Responsible Party. • Third Party defined as someone whose property was affected by contamination emanating from the source property. • DELG responsible to audit/review Site Professional submissions to ensure conformity with the management process.
