Exploratory SurveT br SEP and Stanford Research Institute In 1952. In addition to exploratory surveys made by the Baton Rouge Befinery and Esso Engineering Department* Stanford Research Institute was engaged in 195? to make a survey of the area* to estimate the contribution of nearby Industries to the local pollution problem* and to make a reconmendation on the desirability of a cooperative industry survey pf the industrial area. Conclusions veret : i a. The principal contaminant from the Refinery is black smoke from flares and the burning pit* although occasionally alcohol and ether odors* acid fumes, hydrocarbon vapors* etc** are released but are usually contained within the Refinery* ; b. Verbally and informally the representative indicated that he did not feel a cooperative survey pf the area was warranted. 2* Daily Report, by Dr. Killer. A record of atmospheric conditions around. the Refinery is made each day from observations by three foremen in th 'Oil Conservation Department. These foremen live to the east* south* and west of the Refinery and record their observations of the presence of smoke* dust plumes* or other discharges as they come to work each morning. Observations of any unusual occurrence during the day is also recorded. Immediate attention is given to any abnormal occurrence within the Refinery in order to keep discharges to the atmosphere to a minimum. 3* Quarterly Botannlcal Surveys. Dr. Clair A. Brown of the L.S.U. Botany - Department was engaged more than two years ago to make quarterly surveys of ihe vegetation grown in the Refinery to determine any ill effects of constituents in the atmosphere on plant life* We added a wide variety of shrubs and other plants to those already in the Refinery in order to obtain a more complete study. Over the more than two years we have found some damage to an estimated of the plants* mostly in localised areas. These surveys are continuing. ; i 4* Bi-aonthly Atmospheric Analyses and Surveys. The Kem-Tech Laboratory (Bra. Choppin and West of L.S.U.) was engaged in April* 1953* to stake chemical analyses and dust counts of the atmosphere within the Refinery* including Anchorage and Maryland Tank Farms* During the 2-1/2 years to date no significant concentrations of contaminants (originating in the Refinery) which would be injurious to health or property have been found. These surveys are continuing. B* Additions to Physical Facilities 1* Flare Reduction and Smoke Control. Facilities have been installed to re duce the amount of hydrocarbons going to the flares by about 200 B/D. In addition facilities have been added to inject steam to the flares to eliminate black smoke. Cost of facilities - $215*000. Operating cost Steam injection - $40,000/year. 2* pf Acid Tama.

Reduction ln_Sn)ohe from Oilr Hastes. The amount of hydrocarbons and oily uuste burned in our burning pit has been reduced from about 70 to about 12 B/T). Facilities to accomplish this coat .- $115,000. 4. Redaction of Hydrocarbon Vapors from Storage Tank, hydrocarbon vapors to the atmosphere have been reduced from 1500 B/D in:1947 to 720 B/CD by the installation of floating roof tanks and other: facilities Total cost - $820,000 Total ! il,415,000 of vhich approximately $5Q0;000 vaa Justified solely for redaction in pollution. . ffiHattoxtJm October 24, 1955
