VERTEX provided Facility Closure Services at a Former NW Pipe Facility in Denver, Colorado to make way for the construction of a light industrial park. Services consisted of the following:
Permit Compliance and Closure Services: VERTEX researched and identified all existing permits associated with the facility and developed a compliance matrix by permit type, timing of close-out, responsible party and status. The matrix was used to track progress and ensure that any operating permits are properly closed out prior to NW Pipe vacating the property.
Water Well Abandonments: VERTEX provided industrial well abandonment services as part of the project. The site was served by an approximately 450 foot deep industrial well that required abandonment and regulatory closure. VERTEX abandoned the well by perforating multiple sections of the well casing prior to installing neat cement grout. Well abandonment paperwork was prepared and submitted to the state and closure was filed in accordance with all regulations.
Pre-Demolition Hazardous Material Survey (Destructive Sampling): VERTEX performed a destructive asbestos survey to supplement our initial asbestos survey and comply with the USEPA’s National Emissions Standards for Hazardous Air Pollutants (NESHAP) regulations. The inspection identified visible, accessible ACM that was required to be abated prior to proposed demolition activities. The survey consisted of the following items:
- Observations of friable and non-friable ACM
- Physical assessment of suspected friable materials
- Bulk sampling and laboratory analysis
- Preparation of a Pre-Demolition Asbestos Survey report documenting findings, recommendations and conclusions
Asbestos Abatement, Regulated Materials Removal and Clearance Services: VERTEX performed turnkey asbestos abatement and regulated materials removal activities at the Site. VERTEX also performed the following monitoring services during the completion of abatement operations at the site:
- Visual Inspection of enclosures, barriers, surfaces and containments to ensure complete removal of asbestos-containing materials;
- Air clearance sampling, as required by Colorado regulations, in the containment areas;
- Completed project closeout documentation, including air monitoring results, disposal certification and contractor’s submittal documentation.
Demolition Oversight: This task included the development and implementation of a Community Air Monitoring Program (CAMP) and an Erosion/Site Control Plan The CAMP described and defined the perimeter air monitoring that was conducted during the demolition of the complex and will complied with OSHA regulations promulgated under 29 CFR 1910.120.
During implementation of the CAMP, steps were taken to prevent and reduce fugitive dust and ensure proper precautions were taken to protect human health of the surrounding community during demolition activities at the site. The four main objectives of the CAMP are as follows:
- Protect human health and the environment
- Monitor dust generation using real time monitoring in conjunction with worker health and safety programs (instituted by each subcontractor, not VERTEX)
- Evaluate the effectiveness of dust suppression controls and determine when additional controls are required; and
- Document air quality during abatement and demolition activities.
Project Closeout Services: Upon completion of the project, VERTEX prepared a comprehensive close-out report documented sampling and laboratory analytical results, records of waste disposal activities, load tickets, recycling tickets, submittals, permits, photographs, and approvals associated with implementation of the scope of work.
