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 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).
