Appearances: Norman Mason, Esq. 50 Congress street Boston, lIassaebusetts Attorney representing the Petit over, Buzzards Bay Gas CcmpanY D.P.U. 15972A is a petition of the Buzzards Bay Gas under the provisions of section 10 Chapter 40A of the General Laws :Co]:, a determination by the Department that the present and proposed situation. of the parcel of land located on the South- erly side of White's Path approximately 35oo feet easterly of its intersection with storage and dated facilities in - rotation Avenue and the Liquid Natural Gas (L.NG) eluding similar facilities for propane constructed and to be constructed therein and thereon are reasonably necessary for the convenience and welfare of the public and that said land, structures and gas processil-Ig and storage facilities be exempt- ed from the zoning by-law of the town of Yarmouth. D.P.U. 15972E is similar petition except that two additional propane stor a e tanks are involved and permission is requested to continue to use the two S existing satellite (LNG) tanks for a limited period as permitted in D.P.U. 15972 dated January 15, 1969• cases and under the provisions of section �.45h of C�pter Further, in both 2. 164 of said General Laws approval is requested of the manner in which and the pressures at which all gas will be stored, processed, transported and distributed in connection with the present and proposed (LNG) and propane facilities located on the site in question. The petitioner is a gas company as defined by Chapter 164 of the General iAws and is a public service corporation providing gas service to the town of Yarmouth and several other towns in the Cape Cod area. In the case of D.P.U. 15972A a public hearing was held at the Leverett Wtonstall Building on August 3, 1971. A similar hearing was held at the game location on September 23, 1971-for D.P.U. 15972B. In both cases all parties in in- terest were given an opportunity to be heard and no one appeared in opposition. The estimated peak day send out for 1971-72 is estimated to be 34,900 MCP and w:i.l.1 consist of 16,176 MCF of natural gas and 18,724 MCP of peak shaving gas. N- o additional pipeline gas will be available until 1973-4 when 3000 MCF/day of synthetic (Naptha) natural gas will be supplied by Algonquin Gas Transmission. Com- pany. No further additional, pipeline gas will be available for the foreseeable fixture. Peak load forecasts have nearly doubled since the 1968 hearing. The only vay this peak load can be supplied is by making available more propane and (LNG) aabieh will require the addition of the storage tanks outlined herein. At the time of the D.P.U. 15972A hearing, it was anticipated that the petitioner's 50,000 barrel insulated and lined concrete storage vessel would be conplete and in service and it was proposed that the two smaller (LNG) tanks be converted to propane storage. A similar conerete'tank presently under construction in Rhode Island has developed cold spots on the walls of the structure due to con- traction. These cold spots were anticipated and have now been measured and the necessary changes in design have been made. However, it is too late now to com- plete the large tank for this heating season. Therefore the two small tanks must Continue to be used for (LNG) storage this season but will hopefully be converted to propane storage before the 72-73 season. at has beeome necessary to install 3• two new propane storage tanks immediately and to continue to fill the existing satellite tanks with (LNG) to meet this season's peak. Due to the inability of the petitioner to purchase sufficient quantities of pipe line gas to meet its peak requirements for some time to come it wih be necessary to install more propane storage and continue to use a mixture of propane and (LNG) on days of heavy demand. The petitioner, therefore, proposes to convert the two existing satellite tan°,�s for additional propane storage upon completion of the larger cement tank in early 1972. This will require certain modification of piping systems and controls as well as the removal of the dit,e and the leveling of the diked area. Tb provide peak shaving gas for this heating season (71-72) the petitioner proposes to install two new propane tanks on the site each with a water capacity of 60,000 gallons. They vrill be located in a separately fenced area about 150 feet from, the nearest (LNG) tank. In addition there will be new propane unloading station and pump pad plus a propane air plant. The tanks will be 90 feet 4 5/8 inches overall in length and 10 feet 11 7/8 inches in diameter. The heads will be made of SA-455--B steel and the shell. of SA-515-(O all having a thickness of 0.9375 inches. The tanks will be supported by curved concrete piers increasing the over-- all height to 15 feet and painted white. The propane -air plant will consist of two units, a vaporizer housed in a fiber glass box -like pre --fabricated structure 14 feet in length 11 feet wide and 10 feet high. The body will be 5 feet in diameter and 12 feet in length with a 12 inch stack 18 feet in height above ground. The second building will be similar in design and construction, 18 X 11 X 10 feet Haigh housing the 2 compressors, electrical control panels and related apparatus. Bath buildings will be painted white with blue trim. Construction authorized in D.P.U. 15972 is in process according to plan. However, due to the short supply of pipeline gas, the date of construction for the liquefaction plant has not been set. Originally it was planned to mound the area around the large storage vessel. Present plans, however, provide for a berm of 4. similar height aro,-ind this vessel. In addition, initial plans provided a minimum distance of 300 feet from this tank to the nearest property line. It is now pro- posed to reddue this distance to 237 feet on the side adjacent to the railroad right of way which is well within the limits of our present code. LNG is a relatively new field of cryogenic technology. This Department's first construction and maintenance standards were issued in 1965 and are presently being reviewed. New standards will be adopted in the near Future. The petitioner is aware of this and agrees that when new code requirements indicate the need for improvement in its safety precautions, it will make such improvements. As previously stated the dike presently surrounding the two satellite tanks must be removed and the containment area filled before the tanks can be used for (LNG) at this.location. Diking requirements in existence at that time must be complied with. All fire protection required in D.P.U. 159(2 will be installed and two dry type portable fire extinguishers will be added. Combustible gas detectors will be placed in the immediate area of the new storage vessel outlets and pumps to deter':, any lea -,;age of propane vapors. The site is presently in an industrial zone under the zoning by --laws of the town of Yarmouth and the use of the land for the purpose alleged is not permitted by said by-law. After notice, public hearings, investigation and consideration the Depart -- went hereby DECIDES that the situation of the parcel of land in question and the pro- posed facilities for the storage and processing of propane and the facilities for the liquefaction of natural gas and the storage and regasification of (LNG) and related equipment constructed or to be constructed or modified thereon and therein are reasonably necessary for the convenience and welfare of the public providing there is compliance with the provisions of this order. Accordingly, it is 5 .
