Direct answer
The short answer for Brooklyn, NY
Paving near the Gowanus, sheds at the edge of the Navy Yard, old brownstone coal-bin cellars, and warehouse bays turned into new uses all see spills. Think paint solvents, heating oil, glues, and unlabeled totes from gut renovations. Getting people clear comes first. The Safety Data Sheet (SDS) replaces chemistry on the shop floor. Barriers on paths to the canal and harbor go with FDNY and state Department of Environmental Conservation (NYS DEC) teamwork. The waste shipping record, under federal hazardous waste law (RCRA) where it may apply, and reopen notes for each bay finish the plan. There is no local crew claim and no promised arrival time.

Local planning context
Reused warehouses, auto repair alleys, and brownstone cellars create a mix that Midtown valet guides miss. Here you find stocks of paint and thinner, heating oil tanks, glue drums, piles of batteries, and gut renovation leftovers. Shop managers and supers often see a film on the floor before they read a label. Closing it off and calling 911 matter more than wiping it up before the next shift. Narrow streets and double-parked box trucks make staging hard. Name the bay contacts early, without walking through fumes.
Old industrial sewer lines and trenches by the canal can carry product toward the water under courtyards. Hosing down after hours is a common way a spill grows. Workers follow FDNY on whether to leave the building. An SDS from the supplier, if you can get it without exposure, helps trained crews. NYS DEC and the city DEP set the rules for environmental notice. A big enough oil or chemical release in the canal area may also go to the National Response Center (NRC).
Co-ops and small manufacturers share alleys, so keep messages to the facts: which bay is closed, which drains to avoid, and who waits for fire officials. Log units, staging limits, and who unlocked doors. After recovery, keep the waste test results, the waste shipping record, and written reopen targets for porous brick cellars. A rush order on the shop floor never skips a step.
