Waste Management & Disposal

Contractor Obligations

The contractor shall, at all times, keep property on which work is in progress, and the adjacent property, free from the accumulation of waste material or rubbish caused by employees or the work. This shall be interpreted to mean that the workplace shall be kept excessively clean. The contractor shall be responsible for providing waste receptacles on the job site and informing all employees that no litter will be allowed on the project site. On completion of the construction, the contractor shall remove all temporary structures, rubbish, and waste materials resulting from operations.

Clean Water Act (CWA) - [40CFR 100-140 & 400-470]

The Clean Water Act (CWA) is the basic federal law governing water pollution control in the United States. It regulates discharges into surface waters from all types of sources (municipal, industrial, and non-point sources). The most applicable provisions of the CWA effecting industry include:

  • Spills of oil and hazardous substances
  • National Pollutant Discharge Elimination System (NPDES) Permit Program
  • Stormwater Program

Stormwater Permit Program

The Stormwater Permit Program requires affected facilities to submit applications that include a site map showing the topography of the site, including:

  • Drainage and discharge structures
  • The drainage area of each storm water outfall
  • Paved areas and buildings within each drainage area
  • Areas used for outdoor storage or disposal
  • Each existing structural control measure to reduce pollutants in stormwater runoff, materials loading and access areas
  • Areas where pesticides, herbicides, soil conditioners, and fertilizers are applied
  • Each of the sites hazardous waste treatment, storage, or disposal facilities
  • Springs and other surface water bodies that receive storm water discharges


An estimation of the area of impervious surfaces, the total area drained by each outfall, and a description of the storage, handling, and disposal of significant materials in the 3 years prior to the submittal of the application must also be documented. A certification that all outfalls have been tested or evaluated for the presence of non-stormwater discharges that are not covered by an NPEDS permit must be made, and this certification must include a description of the method used, dates, and the observed onsite drainage points.

Documented Quantitative Data

Quantitative data based on samples collected during storm events must be documented from all outfalls for the following:

  • Any pollutant with an established limit in an effluent guideline to which the site is subject
  • Any pollutant listed in the site NPDES permit
  • Oil, grease, PH, BOD, COD, TSS, total phosphorus, total nitrogen, and nitrate plus nitrite nitrogen
  • Flow measurements or estimates of the flow rate, and the total amount of discharge from the storm event(s) sampled and the method of the measurement
  • The date and duration of the storm event(s), sampled and rainfall measurements, and the duration between the storm event sampled and the end of the previous measurable storm event(s).
