{"abstract":"This Final Rule makes changes in some of the corrosion control standards for hazardous liquid and carbon dioxide pipelines. The changes are based on our review of the adequacy of the present standards compared to similar standards for gas pipelines and acceptable safety practices. The changes are intended to improve the clarity and effectiveness of the present standards, and reduce the potential for pipeline accidents due to corrosion.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"Research and Special Programs Administration","name":"Research and Special Programs Administration","id":451,"url":"https://www.federalregister.gov/agencies/research-and-special-programs-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/451","parent_id":492,"slug":"research-and-special-programs-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2001/12/27/01-31655.html","cfr_references":[{"chapter":null,"citation_url":null,"part":195,"title":49}],"citation":"66 FR 66994","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This Final Rule takes effect January 28, 2002.
