I a a DATE : AUGUST 7, 1978 TO : CITY MANAGER FROM: Administrative Assistant SUBJECT: ENCIMA POWER PLANT FALLOUT: DAMAGE CLAIMS The City Council, at its February 7, 1978 meeting, adopted Resolution 5302 (Attachment 1) finding . . . "that the particul fallout problem from the Encina Power Plant has been controlled to the satisfaction of the City Council of the City of Carlsbad and of the Air Pollution Control Officer and that Condition No. (HI, of Ordinance No. 9456 has been satisfied provided that, un final building permit clearance is obtained for Encina Unit No. San Diego Gas and Electric continues to pay claims for property damage resulting from the "fallout" and San Diego Gas and Elect furnishes the City Manager with such information as he may requ in order to report on such damage and the payment of claims theref or. 'I In order to develop thorough and independent data on the amount damage allegedly caused by fallout from the Encina Plant, it wa decided to conduct a survey of households in the Terramar area. The SDG&E Company agreed to fund the cost of the survey. The survey was to be performed by a firm selected by the City of Ca In March, 1978, the firm of Economic Behavior Analysts, headed . Dr. Oscar Kaplan, was hired to survey the Terramar neighborhood The field work for the survey took place between April 7 to May 1978. A report of the survey is attached as Attachment 2. The individual survey sheets for each household contacted were retu to the City of Carlsbad and analyzed in order to identify unres complaints or claims. Upon analysis of the information on the survey sheets, the San Diego Gas and Electric Company was asked investigate complaints or possible complaints from sixty-nine ( households. After the company's preliminary review, a list of twenty-one (21) households with complaints or unresolved claims developed for further investigation. Only households with a sp complaint were included for further investigation. i 0 a ENCINA PObiJER PLANT FALLOUT: DAMAGE CLAIMS August 7, 1978 Page 2 In order to establish the validity of the complaints and unresolved claims, the services of an independent scientific laboratory to conduct an investigation were required. The San Diego Gas and Electric Company agreed to fund the cost of this investigation and study and further agreed to pay for any damages that the laboratory, as a result of its investigation, attributed to fallout from the Encina Plant. The firm of Truesdail Laboratories, Incorporated, Los Angeles, was retained to perform the requested services, Truesdail has extensive experience in forensic investigation and testing, as well as pollution and fallout investigations related to power plants. Mr. Ignas Bandziulis, Supervisor, Air Pollution Testin( conducted the investigation and testing on behalf of Truesdail. In addition to the twenty-one (21) households referred to Truest for investigation, during the course of the investigation, four additional households were also investigated. Mr. Bandziulis's report is attached as Attachment 3. A meeting was held in the City Hall Conference Room on July 11, 1978 to discuss the results of Mr. Bandziulis's investigation. In addition to Mr. Bandziulis and City Staff, Mr. Schatzinger, representative of the San Diego Gas and Electric Claims Departr was also present. The findings of Mr. Bandziulis's investigati of the 25 households in question were reviewed and it was deter that investigation had identified four households with apparent valid claims. After review of Mr. Bandziulis's findings, the c representative of SDG&E agreed to contact and attempt to settle the claims of three households that had property damage that tl? investigation indicated were due to the fallout from the plant. The company's claim representative indicated that it would be useless to contact the fourth household at this time since the homeowner had previously clearly indicated to Mr. Schatzinger t he was not willing to settle the claim. In the other 21 cases investigated, there were a few allegations of damage, but since they could not be attributed to fallout damage from the plant, further settlement discussion by the SDG&E Company were request On August 4, 1978, the claims representative of SDG&E Company, Mr. Schatzinger, was contacted regarding the result of his attc to settle the claims referred to him at the August 11, 1978 me€ Mr. Schatzinger indicated that claim settlements had been acceg by the three households in question. C a 0 ENCINA POWER PLANT FALLOUT: DAMAGE CLAIMS August 7, 1978 Page 3 Mr. Schatzinger also supplied information regarding the SDGStE Company's claims activity associated with Encina fallout problen AS a result of the survey findings and previous claims investi- gation by the company, Mr. Schatzinger has contacted 122 househc in the Terramar area regarding possible fallout damage claims. of these contacts, 63 households made no claim against the comp~ The remaining 59 households contacted asserted a claim for damas of one sort or another. Mr. Schatzinger indicated that the following action to settle claims resulted from contacting those households making claims: 46 Autos - cleaned and/or polished to remove stains. 9 Houses - a portion or all of the woodwork was repaint 1 Auto - fully repainted. 1 Auto - plastic window replaced. 1 Swimming Pool - cleaned, 4 Cash settlements. Mr. Schatzinger further indicated that during the past calendar years, the following amounts have been disbursed in settlement c fallout damage claims attributed to the Encina Plant: 1976 - $15,032 1977 - $ 4,329 1978 - $10,850 As a result of the door-to-door survey of the Terramar area, all households with current claims of fallout damage have been identified. Based on the information produced by the survey and Truesdail Laboratories' investigation, it appears that in all bu one instance, the SDG&E Company has reached a settlement with th W w ENCINA POWER PLANT FALLOUT; August 7, 1978 Page 4 DUaGE CLAIMS households having apparent valid claims. The one homeowner wit1 an apparent valid claim with whom the company has been unable tc settle, apparently intends to seek a legal remedy in the future, Although not every householder in the Terramar area may be total satisfied, it appears that the SDG&E Company has made a reasonal effort to fairly deal with claimants and potential claimants. 1 appears that where evidence exists that the SDG&E is responsiblc €or fallout damage, the company has made a good faith effort to reach settlement with the claimant. % FRANK N.

Painted copper rain gutters - from the ocean side, there is quite strong corrosion. There appears to be not much adher- ance of paint to the metal. The gutters and the woodwork was repaired about eighteen months ago. The painted surfaces show deterioration - particularly on the upper surfaces. Woodwork on the deck was painted in 1976. 2. On site examination: Microscopic analysis using 30X magnification. There are quite a few carbon cenospheres and carbon cenosphere aggre- gates. Some of the aggregates showed disintegration upon impact. No acid fallout particles were found. Mr. William Barlow offered the following suggestions: 1. The soot is continuous problem in this neighborhood. soot blowing should be started only when sufficient strength of wind is present and in the directions to the East: or the West only, where the fallout would cause the least harm.

Generally, the fallout is washed from the roofs and the cemented surfaces. Due to the indentation in the backyard cement floor, the pool of water stays there. Upon evaporation, she collected the black residue into plastic bags. Her cement driveway is spotted by iron oxide stains. Analysis of the submitted deposits: The deposits contain a large portion of broken vegetable matter (possible kelp). This makes the deposit float on water. Among this vegetable material there are particles of white and black sand. It is not possible to find any acid fallout in this kind of the sample Also, there are some cenospheres. due to the exposure to water. Water extracts all the acid materials and also water soluble metal salts. However, it clears up the mystery of why the fallout floats on water.

The usual claim is that this fallout is caused by the neighboring plant. People lived on the seashore further down the coast and this fallout was not as great as in this location. Fallout, in this case, includes all of the dust settling on the properties. The investigation did not uncover the plant as being the major contributor to the fallout. Most of the fallout dust is of the common variety: sand or clay particles and vegetable origin matter. The be quite large at this relatively short distance from the plant. The sedimentation rate of the smaller particles is slow and, thus, they are expected to settle further from the plant. electric power plant (steam boiler) fallout particles are expected to Most of the complaints were based on the past. The present problems appear to be less pronounced. The acidic particle fallout was found only in one case, on Mr. Valentine's property. There were only a few particles Most of the particles are dry and neutral, usually found in the carbon cen sphere shape. On longer contact with the surface, these cenospheres may stain the surfaces due to the water extractable iron salts in those sphere However, not all of the cenospheres are capable of this staining. The relative humidity is a problem at the seashore. Fungus growth in the shaded areas is always a danger. Once the fungus appears, it ought to be cleaned and the surface sterilized (chlorine bleach works satisfactoril Then the paints used ought to contain fungucides. Sea salt spray has a strong corrosive action on aluminum window or screen frames. Only well, anodized aluminum frames would resist the wea- thering. It is most difficult to distinguish the differences between the ocean spray and plant fallout corrosion. Ocean water also contains sulfat as does the plant fallout material. One of the tests of anodized aluminum quality control is a submission of aluminum test panels to the salt water fog in a test chamber. Unless the actual fallout particle is found on the frame in an acid corrosion pit, one cannot say that the aluminum corrosion was caused by the plant fallout. On the other hand, the cubic salt crystals were always present on the aluminum frames or in the screens. The cubic form is typi- cal for salt (NaC1) crystals. The almost complete absence of cenosphere aggregate particles indicat that most of the plant fallout is from a normal plant operation. The heal iest fallout particle population is reached during so-called soot blowing operations in the plant. Apparently, this operation is handled during the favorable wind conditions, the larger particles and cenosphere aggregates. These particles are prodt by depositing a particulate matter (soot) on the heat exchange surfaces ir side the boiler and later blowing them off, thus resuspending these deposj in the flue gas stream during the soot blowing operations. This resuspenc particulate matter is carried out into the atmosphere through the stack. The soot blowing fallout is characterized by L TRUES DAIL LABORATORIES. INC. -61- Laboratory No: 21359 I I I I I I I I I I I I I m I I I The soot blowing operation usually causes most of the fallout in the neighborhood due to the increased particle size and the increased particle numbers. During the normal plant operation, the particles emitted are smaller in size and it takes time for these particles to reach ground from the top of the stack level. The group of this type of particles is tagged by single cenospheres (not aggregated). This last group of particles have a much smaller percentage of acidic particles than the particles from soot blowing operation emissions. Particles as a health hazard is a very remote possibility. The healt hazard is created by the particles of 5 microns or less (usually 2 microns or less) and in the concentrations above 5 mg/m . These particles act al- 3 I most like gases. A tall stack insures the flue gas emission at a fairly high level above ground. Settling rate of the small particles is very slow. During that time, either they are dispersed by the wind or slowly aggregate and settle (fallout) as a larger particle. Therefore, the fear of the health hazard ought to be discounted. Some additional fallout dust is caused by the construction project.
