The sampling manholes may be used in lieu of a cleanout, but never the reverse. A manhole at the connection of the site lateral to the public main may not be used as a sampling manhole. The requirement to use the larger manhole will be noted in the conditions of approval for the project. Metering manholes, per City Standard Drawing PRIV-5, must be constructed where one of the following criteria apply: 1. The potential user is one of the 34 NRDC industries for which USEPA intends to set Categorical Standards (and is not in an exempt subcategory). 2. The average flow exceeds 25,000 gallons per day (gpd) or the average BOD5 or suspended solids loading exceeds 50 pounds per day. 3. The average flow exceeds 2,500 gpd, and priority pollutants or prohibited discharge pollutants are known to be present. 4. The average flow is less than 2,500 gpd, and priority pollutants or prohibited discharge pollutants are known to be present in significant concentrations. 5. The potential user either is known to have caused, is suspected of having caused, or has the potential to cause, operational problems at the Dublin San Ramon Services District (D.S.R.S.D.) wastewater treatment plant. Specific determinations on what classes qualify for the above will be made by the D.S.R.S.D. Industrial Waste Inspector. E. Fire System: 1. Review and Approval: The Fire Marshal must review and approve onsite fire systems, including system layout, appurtenance location, fire hydrant spacing, etc. Shop drawings must be submitted by the fire sprinkler contractor to the Fire Marshal for final approval prior to commencing installation of any part of the system.
