Meza, Mayor THE CITY OF LA PORTE 124 South Second Street La Porte, Texas 77511 3636 RICHMOND AVENUE HOUSTON, TEXAS 77046 Bir,` 700 RE: DOW'S PROPOSED 16" HYDROCARBON PRODUCTS PIPELINE ACROSS AND WITHIN THE CITY OF LA. PORTE,_TEXAS Dear Mayor Meta: Please refer to our letter of June 8, 1978 regarding our initial formal request for the above captioned pipeline,. for your. review and approval. The products to be transported initially through the proposed 16" pipeline are naphtha, fuel oil and kerosene. The proposed 16" pipeline will be constructed of O.D. x - 65, 0.354" wall thickness, ERW carrier pipe. The pipeline will have a maximum operating pressure of 1,440 psi, which is only 5C% of yield strength. The DOT Spec. 195, Section 105, allows an operating pressure of 72% of yield strength. This pipeline shall be installed in a manner so as to tt>aintaire a minimum depth of 48" of cover below the natural surface of the ground to the top of the pipe. In addition, where the proposed pipeline wi7.I crass and affect drainage ditches,. bayous and streams, eta. it will be in- stalled to maintain a minimum depth of 60" of cover below tha bed of the stream to the top of the pipe. At bayou crossings, the pipeline will be coated with concrete to increase its safety. All Federal State and local construction requirements will be satisfied by Dow Chemical, as well as any additional good pipeline construction practices. Dow meets or exceeds all known safety standards in the design and construction of its pipeline system, and this proposed pipeline will be so designed. It is our intention to prevent ;:ipeline ruptures by initiating a very extensive testing program before any pipeline is put into service. After a pipeline system is placed into service, a closely monitored cathodic protection program is carried on far the w ~RI `~`DtE YmiOt AN OPtRATING UNIT OP THE DOW CHEMICAL COMPANY
