VERTEX was retained to assist in the redevelopment of this approximately 14 acre property that historically operated as a commercial nursery and landscape business dating back to the early 1960s. The site operations historically utilized several underground storage tanks (USTs) for fleet vehicles and heating of facilities on-site.
The project included completion of an ASTM Phase I Environmental Site Assessment, a Phase II Limited Subsurface Investigation and Flammable Gas Investigation, a Hazardous Material Survey and subsequent asbestos abatement management, UST removal/closure and pursuit of regulatory closure as well as structural demolition oversight and construction support consulting. Highlighted services included the following:
Phase II LSI & Flammable Gas Investigation: VERTEX performed a Phase II LSI and flammable gas investigation on-site to assess the potential for a release from on-site UST systems as well migration of contaminants from upgradient off-site sources as well as the presence of flammable gas on-site as a result of the historical presence of landfills in the immediate vicinity of the site.
Asbestos Abatement, Regulated Materials Removal and Clearance Services: VERTEX performed turnkey asbestos abatement and regulated materials removal activities at the Site including the abatement of plaster walls, vinyl floor tile, window glazing, textured concrete, vinyl sheet flooring, drywall systems and transite. 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.
Environmental Remediation/UST Removal & Closure: This task included enrollment of the site into the Colorado Department of Labor and Employment-Division of Oil & Public Safety (CDLEOPS) Leaking Underground Storage Tank (LUST) program. The remediation included the characterization, delineation, management and oversight of the UST closures as well as excavation and disposal of contaminated soils identified on-site. Additionally, VERTEX prepared and submitted necessary regulatory documentation documenting closure activities. Upon completion of the environmental remediation efforts, VERTEX obtained a No Further Action (NFA) through the CDLEOPS LUST program for the client as a result of the successful remediation and closure of the on-site UST systems.
The project was completed on-time and under budget. VERTEX’s consulting and guidance throughout the project provided the client with the ability to navigate complex on-site environmental issues, achieve and maintain compliance with local, state and federal regulations and maintain the project timeline.
