The plan was prepared in response to Waste Discharge Requirement Order No. 5-01-114, Prohibition A.8 that required a report describing preparation of the area prior to land application of wastewater in that area. Upon review of the initial submittal of the report, staff informed Pilkington North America that because technical reports required by the WDRs had not been submitted, use of Site B could not be approved. The technical reports were submitted on 18 September 2002. Pilkington has recently requested the use of Site B be again reviewed and resubmitted the 7 November 2001 Report on Site B on 25 October 2004. The use of Site B is described in Prohibition A.8 which states: The discharge of wastewater to Site B is prohibited until the Discharger has submitted, and the Executive Officer has approved, a report describing the improvements made to this area (i.e. the wastewater distribution system, berms,fencing, signs, land leveling, and crop planted) so that wastewater may be applied in conformance with this Order. I have the following comments on the submittal: • It is not clear that berms exist at the east side of the Site B. Please submit photographs of the area that show berms are surrounding Site B. • The signs must be installed prior to authorization to begin applying wastewater to Site B. Please submit photographs of the installed signs. • A fence is shown at the northwest portion of Site B in Figure 3, but that is inadequate to determine if public access to Site B is limited. Please describe how the fence and signs comply with Discharge Specification B.6 which requires: Public contact with reclaimed water shall be precluded through such means as fences, signs, and irrigation management practices. Signs with proper wording ofsufficient size shall be placed at areas of access and around the perimeter of all areas used for wastewater disposal to alert the public of the use of reclaimed water.
