Pre renovation Information Regarding Designated Substances

Transcription

1 Pre renovation Information and Specification Sections for Designated Substances City of Thunder Bay Current River Park Picnic Shelter and Washrooms 570 Cumberland Street North, Thunder Bay, Ontario Pre renovation Information Regarding Designated Substances True Grit Consulting Ltd. (TGCL) has completed, at the request of the City of Thunder Bay (COTB), a limited pre renovation designated substance survey (DSS) for the picnic shelter and the floor of the washrooms at Current River Park, located at 570 Cumberland Street North in Thunder Bay, Ontario. TGCL understands that renovations planned for the two buildings include the following: preparing and repainting wood and metal surfaces in the picnic shelter; replacing the roofing on the picnic shelter; and preparing and repainting the concrete floor of the washrooms. Methods used in the limited DSS are attached along with laboratory certificates of analysis. Asbestos is not expected to be present in the building materials that will be disturbed as part of the planned renovations. Wood, concrete and metal surfaces that will be disturbed are not considered to be potential asbestos containing materials. The roofing on the picnic shelter is reported to have been installed in 2001 and is not expected to contain asbestos. Lead The following paints in the subject areas were identified as lead containing: o o o white paint on the wood ceiling of the picnic shelter; blue paint on the metal columns of the picnic shelter; and grey/red paint on the concrete floors throughout the washrooms. The lead containing building materials have not been submitted for toxicity characteristic leaching procedure (TCLP) analysis. Contractors will be expected to collect the debris generated as part of the surface preparations and that material will be submitted for TCLP analysis. Specifications for potential disturbance of identified designated substances in the work area are attached. The onus is on the Contractor to select the appropriate removal method to satisfy the regulatory requirements and the attached specifications. PROJECT NO: A AUGUST 2016

2 Methods and Notes for Limited Pre Renovation DSS

3 Methods for Limited Pre Renovation Designated Substance Survey (DSS) Visual Assessment A site inspection was completed by Mr. Mike Broere, M.Sc., TGCL Air Quality Scientist on August 22, It involved a visual assessment of the subject area for building materials that could contain asbestos and lead. Previous Reports A designated substance survey (DSS) was completed for the Current River Washroom building in November 2014 by TGCL. The TGCL report for that DSS (TGCL Report Number A 074), entitled City of Thunder Bay, Designated Substance Survey, Current River Park Washrooms, 570 Cumberland Street North, Thunder Bay, ON and dated, February 12, 2015, was reviewed as part of the current investigation. Asbestos Building materials not already identified in the existing reports and suspected of containing asbestos were collected and sampled in accordance with Ontario Regulation (O.Reg.) 278/05 Designated Substance Asbestos on Construction Projects and in Buildings and Repair Operations. Samples were analyzed via Polarized Light Microscopy (PLM) following the U.S. Environmental Protection Agency Test Method EPA/600/R 93/116: Method for the Determination of Asbestos in Bulk Building Materials, June Where samples consisted of more than one distinct layer (i.e. vinyl floor tile, paper type backing, mastic, etc), each layer was analyzed and reported separately. Materials found to contain 0.5% or more asbestos were identified as ACM (as per Ontario Regulation 278/05). All work involving ACM must follow procedures specified in Ontario Regulation 278/05 (O. Reg. 278/05). Transportation of ACM (e.g. for disposal) can only be done by a Ministry of Environment and Climate Change (MOECC) licensed carrier. ACM can be disposed of in a licensed landfill willing to accept it. Lead Lead can be expected to be found in older paints, in pipe joint solder or as domestic water service piping. Materials not already identified in existing reports as lead containing were collected and submitted for laboratory analysis of lead content by a qualified laboratory according to a standard method (acid digestion, inductively coupled plasma (ICP) elemental analysis). The Canadian Hazardous Products Act (CHPA) is responsible for defining surface coatings (including paint) as lead containing. The CHPA definition of a lead containing surface coating is one that contains more than 0.009% lead (weight %). Note that laboratory analysis of materials allows identification of lead content as low as 0.009% lead; however, instantaneous spot check methods have a detection limit of 0.06% lead. Materials identified as non lead containing using the spot check method must be treated as possibly lead containing since the detection limit for the method is greater than the definition of a lead containing paint. Determination of lead content of painted materials is included in the DSS in order to specify work procedures and disposal considerations. Work involving building materials identified as lead containing must follow procedures outlined in the Ontario Ministry of Labour (MOL) document, Guideline Lead on Construction Projects, dated 2004 (MOL Guideline). Lead containing materials must not be disposed of until a representative sample of the material is subjected to toxicity characteristic leaching procedure (TCLP) analysis to determine if it is leachate toxic according to Schedule 4 of Ontario Regulation 347 (O. Reg. 347). Non metallic materials that were found to contain greater than 0.009% lead were submitted for TCLP analysis. Note that metallic materials found to be lead containing are not normally submitted for TCLP analysis, since it is standard practice to recycle metals as opposed to disposing of them and there are no restrictions on recycling metals with lead coatings.

4 Lead waste must be transported for disposal by an MOECC licensed carrier. Non leachate toxic lead waste can be disposed of in a licensed landfill willing to accept it. Leachate toxic lead waste must be transported to, and disposed of or destroyed at, a licensed disposal or destruction facility. TRUE GRIT CONSULTING LTD.

Each sample must contain at least 50 grams of representative waste material..2 Submit the collected samples under chain of custody to an accredited laboratory for lead analysis and subsequent toxicity characteristic leachate procedure (TCLP) analysis for lead according to the requirements made under O. Reg If the results of analysis are less than 5 milligrams lead per litre (mg/l) in the leachate then the material can be disposed of as a non hazardous waste..1 Arrange for transportation and disposal of all removed LCM (Please refer to Section 1.8 above)..2 Clean up:.1 Frequently during Work and immediately after completion of work, clean up lead containing dust and waste using HEPA vacuum..2 Place lead containing dust and waste in sealed dust tight waste bags or drums. Treat drop sheets and disposable protective clothing as lead waste and wet and fold to contain dust and then place in waste bags.

23 Type 2 Operation Intermediate Precautions August 2016 PAGE 7 OF INSPECTIONS.3 Immediately before their removal from Lead Work Area and disposal, clean exterior of each filled waste bag or drum using damp cloths or HEPA vacuum. If using bags, place in second clean waste bag..4 Seal and remove waste from site. Dispose in accordance with requirements of Provincial and Federal authority having jurisdiction. Ensure that dump operator is fully aware of nature of material to be dumped and that guidelines and regulations for lead waste disposal are followed..5 Perform final thorough clean up of Lead Work Areas and adjacent areas affected by Work using HEPA vacuum..1 The following visual inspections will be completed by the Consultant over the duration of the work. The Contractor is to provide minimum 24 hours notice to the Consultant to arrange for the inspections. Lead Abatement Work shall not proceed until each inspection is completed and approval to proceed is obtained from the Consultant..1 Initial Inspection: following completion of hoarding erection but prior to the commencement of lead paint removal..2 Clearance Inspection: following completion of all removal work and cleaning of all surfaces within the enclosure, but prior to application of sealant and removal of hoarding..2 If results of the visual inspection suggest that coatings have not been removed to the extent practicable then, repeat steps described in Sections 3.2 and 3.3 and any additional direction provided by the Consultant. Re cleaning shall be at no additional cost to the Client and shall be borne by the Contractor. END OF SECTION
