Nomellini Construction Company page 2 1045 W. Charter Way, Stockton May 12, 2009 Previously the EHD approved a request to modify the quarterly sampling and reporting requirements for this site . Recent financial constraints at the State Water Resources Control Board (SWRCB) Clean Up Fund (CUF ) have caused hardship on responsible parties and many, including yourself, have requested reductions in quarterly monitoring and reporting in order to reduce costs. The recent approval by the EHD for this site included reducing the reporting and monitoring from quarterly to annually for some monitoring wells and semi-annual sampling and reporting for other wells . There appears to be some confusion with sampling and monitoring and the EHD offers this clarification . Please be aware that the sampling and laboratory analyses of ground water samples may be reduced by the EHD , but the California Code of Regulations , Title 23, Section 2652(d ) requires owners of contaminated underground storage tank sites to report quarterly on the status of their site to the lead regulatory agency overseeing the investigation (monitoring). The report must include an update on specific information and results of all corrective action (investigation) which has occurred during the period . An item that must be discussed in each quarterly report is future investigative actions and a time schedule for implementing the actions . You may prepare this report yourself unless geologic or engineering interpretation is included which would require that it be prepared by an appropriately registered professional . Monitoring well sampling events that have been previously approved for a reduction to annual or semi-annual events may remain on this schedule for laboratory sampling only. But a quarterly status letter-type report (monitoring ) is still required . For the quarters where the annual or semi-annual events are not conducted , a letter-type quarterly report is required to be submitted to Geotracker for the EHD to review. I hope this clears up any misunderstandings with your monitoring , reporting and sampling requirements. Thank you for your cooperation in continuing to investigate this site .
