Several culverts and <br />structures have required regular maintenance to ensure continued function of the system. An increased <br />inspection frequenc~voluntarily adopted in 2003 in order to identify excessive sediment accumulations in these <br />structuresprior to non-functionine condition continues to be implemented. This practice has reduced the <br />possibility equipment availability and manpower restrictions could delay maintenance when these structures <br />approach non-functioning condition. <br />Time has been allocated for training employees how to spot potential Storm Water Management Plan violations <br />or non-functioning conditions during mandatory Annual Refresher Training Specific guidance as it relates to <br />spills and >;eneral system function has also been provided to employees and contractors working on site. <br />Note -form maybe reproduced Page 1 of 3 ar6N6i1 <br />CF 21.6.4 <br />
