BLUEBOOK - Natural Gas & Electricity

1 BLUEBOOK SPECIFICATIONS AND REQUIREMENTS FOR GAS INSTALLATIONS RHODE ISLAND June 22, 2010 IMPORTANT NOTICE REGARDING NATIONAL GRID SPECIFICATIONS AND REQUIREMENTS FOR GAS INSTALLATIONS These Specifications and Requirements have been designed with great care so that, when followed consistently, they will ensure that a new installation will comply with Rhode Island law, IFGC (International Fuel Gas Code), various codes and other safety requirements. Failure to comply may result in a code or safety violation and/or a job not being approved. Therefore, delays could result while the contractor corrects the changes at his/her expense. The specifications, construction standards and other requirements contained in this book represent National Grid commitment to the contracting community for quality and consistency of service. Any variation from the type of hardware used, connection point of service, service entrance or other details on a construction standard must be approved in advance by National Grid in writing.

2 We at National Grid are always available to discuss your design concerns and to provide assistance to you. We encourage any questions regarding your problems on specific projects, please be sure to contact us for our input during the planning stages to avoid possible additional costs later in the job.
