82 SAFETY REGULATION FOR SMALL LPG DISTRIBUTION SYSTEMS The review and assessment proved challenging because of the limited data on these small LPG systems, especially data that would allow for the assessment of specific federal regulatory requirements with regard to their safety effects and compliance burden on operators of small systems. After recapping the key points and findings from these earlier chapters, this chapter contains the committee's advice to Congress and PHMSA on ways to make more informed decisions about the regulation of small LPG pipeline systems.

88 SAFETY REGULATION FOR SMALL LPG DISTRIBUTION SYSTEMS extent to which the requirements are being complied with and effective in controlling risks. Given this evidence of variability in regulatory implementation and lack of assurance that many small LPG systems are indeed complying with the federal regulations, the committee believes that it would be a mistake to view the current regulatory regime as being operative and that steps should be taken to better identify small systems to ensure that regulatory requirements and their enforcement are appropriate to the safety risks they present.

SUMMARY REVIEW AND ADVICE 89 • Require that states periodically seek permission from PHMSA to renew their waiver programs by providing evidence that public safety has not been compromised by the waivers. CONCLUDING COMMENTS The committee believes that its recommendations are complementary and will work together to inform sound decisions about the application of regulatory requirements and their enforcement.
