We prepare all required reports, agency submissions, and closure documentation so you have a complete, defensible project record.
Allied All-City's environmental division covers a broad range of services: 24/7 emergency spill response and containment, Phase I through Phase III environmental site assessments, underground and aboveground oil tank testing, cleaning, and removal, petroleum and chemical release remediation, industrial and hazardous waste disposal, and vactor and guzzler vacuum excavation services for liquid and solid waste removal. We serve residential homeowners, commercial property owners, municipalities, industrial facilities, and real estate professionals across Nassau and Suffolk Counties. All work is performed by our own licensed environmental staff — no subcontracting.
Allied All-City maintains 24/7 emergency response capability. When you call with an active spill or release, you reach our own staff, not an answering service, and we mobilize our crew from there. Response time depends on your location and what's already on the road, but we prioritize emergency calls and aim to have personnel on-site as quickly as possible. Speed matters in spill response because contamination migrates — the faster containment is established, the smaller the affected area and the lower the overall cost of cleanup. Our crews arrive ready to deploy containment equipment, recovery units, and any regulatory notification support you need during the incident.
A Phase I Environmental Site Assessment is a records review and site reconnaissance that identifies recognized environmental conditions — past uses, known contamination, regulatory listings, and other factors that suggest a potential environmental issue. Phase I assessments do not involve any soil or groundwater sampling; they're a documented professional evaluation of what the available records and site conditions indicate. If Phase I findings warrant further investigation, a Phase II assessment adds physical sampling — soil borings, groundwater monitoring wells, or both — to characterize what's actually present in the ground. Phase III is the remediation phase, where confirmed contamination is addressed through excavation, treatment, or other approved methods through to regulatory closure. These assessments are required by lenders and buyers in commercial real estate transactions and by regulators in response to reported releases.
We handle oil tank work for residential properties throughout Nassau and Suffolk Counties, and it's one of the most frequent requests our environmental division receives on Long Island. Residential oil tanks — particularly the older steel underground tanks common in homes built before the 1980s — are a significant environmental and financial liability. When a tank fails tightness testing, shows visible corrosion, or is discovered during a property sale or renovation, homeowners need a licensed contractor who can handle the testing, cleaning, removal, and any associated soil sampling and reporting without delays that derail a real estate transaction or stretch out the regulatory timeline. We work directly with homeowners, their attorneys, and real estate agents to keep the process moving.
Vactor and guzzler units are industrial vacuum excavation and liquid waste recovery vehicles. A vactor truck uses high-pressure water and a powerful vacuum to excavate soil around buried utilities and structures without the damage risk that conventional mechanical excavation creates — it's the preferred method when digging near gas lines, water mains, or electrical conduit in a congested utility corridor. Guzzler units are configured for high-volume liquid and slurry recovery — removing the contents of wet wells, catch basins, holding tanks, lagoons, and similar structures. These services are used by municipalities for infrastructure maintenance, by industrial facilities for tank and pit cleaning, and by contractors who need to safely expose buried utilities or remove accumulated waste from confined spaces. Allied All-City operates these units with its own crews across Long Island.
Regulatory documentation is something we handle as part of every environmental project, not as an afterthought. For spill and release response, we prepare the required NYSDEC spill reports and any other applicable agency notifications. For oil tank removal with soil contamination, we manage the notification, sampling, remediation, and closure documentation required to get a site officially closed out with the DEC. For site assessments, our environmental staff prepares reports that meet the standards required by lenders, attorneys, and regulatory agencies. We've been working within New York State's environmental regulatory framework on Long Island for decades, and our documentation is built to hold up under scrutiny — because that's what protects our clients when they need it most.
