<br />Chapter 4-Site-Specific Industrial Storm Water BMPs <br />Mechanical and electronic equipment should be operated and maintained according to the <br />manufacturers' recommendations. Equipment should be inspected regularly to ensure proper and <br />accurate operation. <br />The pollution prevention team, in consultation with a certified safety inspector, should evaluate <br />system monitoring requirements to decide which systems are appropriate based on hazard <br />potential. <br />is <br />Advantages of Preventive Monitoring Practices <br />• Pressure and vacuum testing can locate potential leaks or damage to vessels early. The <br />primary benefit of such testing is in ensuring the safety of personnel, but it also has <br />secondary benefits including prevention of storm water contamination. <br />• Automatic system monitors allow for early warnings if a leak, overflow, or catastrophic <br />incident is imminent. <br />• Manning operations, especially during loading and unloading activities, is effective and <br />generally inexpensive. <br />• The primary benefit of nondestructive testing is in ensuring the safety of personnel, but it <br />also has secondary benefits including early detection of the potential for contaminating <br />storm water runoff. <br />Disadvantages of Preventive Monitoring Practices <br />• Plant personnel often do not have the expertise to maintain automatic equipment. <br />• Automatic equipment can fail without warning. <br />• Automated process control and monitoring equipment may be expensive to purchase and <br />operate <br />4-39
