Report on Investiga.tion of Air Pollution, Brown ð: Brown Const. Co. - pa.ge 3 By J. L. Mayes a.nd JBIIII:IS F. Aiken, Jr. April 28, 1953 Observations I 1. The asphalt paving mix plant is located on the south side of the II1ssouri Pacific Railroad tracks north of llorth Street between Chester and Francis A'Yenueh !he pla.nt 18 a. hot-mix pla.nt. Materials used and process i8 as followsa Materials - (1) The a.ggrega.te used is ohert from southeast Kans.. dno and lead !II1n1nc and milling operations. (2) Asphalt, penetration 85-100. Prooess - (1) The ohert is dried in .. rotery kiln at .. temperature "tween 271° and 1000 P. The maximum teçerature allowed is 3250 F. The kiln 18 tired by a Datura! p8 filllll8. Air is drawn through the kiln in oourrtertlow to the chert. FrO1l1 the kiln, the air, carrying steam. am dust and ezhauat gases, puses throu¡h two cyclone dust collectors, a suction tan and then to the exhaust stack. 'lhe ex- haust stack is about 20 feet long a.nd the top of the stack is about ao teet tr- the ground. (2) The dried, hot chert puses, by gravity, from the lower end of the kiln to a.n elevator which raises it to 8. hopper from which it is fed into the mixiDg chllDlber to be mixed with hot asphalt. (3) Asphalt is heated to a temperature of 2750 to 3000 F. in a large ta.nk, by means of heating coils carrying hot oil. From the heating tank, the aaphalt is piped to a p~ which discharges the hot asphalt into the mixing chamber where it is mixed with the hot chert. (4) The hot chert and hot asphalt are mixed in the m1x1Dg ohlllllber, the Jllb:ød product is disohar gad to a conveyor belt and the conveyor belt disoherges the finished mix into trucks for conveyance to the job.

The erea affected by discharge from the plant stack. on the day of the 1.mesti- gation, wa.s principally the properties occupied by the Case snd Johnaon femilies directly north of the plant across the Missouri Pacific Railroad tracks. 7be Case home address wa.s 600 Chester and the Johnson properties were at 604 am 608 Chester. The variBhle wind, from the south, carried the stack diaoherge back snd forth (from east to west) across these properties. sometimes at ground level and so-ti_8 at a higher elevation. Discussions General. It should be borne in mind that the determinatioISreported here represent oon- ditions during the time of sampling and on one day. For this reason, the results obtained cannot be considered as conclusive or average. For such evaluation, i Report on Investigation of Air Pollution. Brown &: Brown Const. Co. - page 4 By J. L. Mayes and Jamøs F. Aileen. Jr. April 28. 1953 many samples should be taken, over an extended period of time. which would inolude all of the conditions of plant operation. season and weather. However, the deter- minations do ghe some idea as to the order of magnitude of the air pollution. Dust Concentration. . The chert used as aggregate is known to contain about 90 per cent fi'ee dUoa (Si02). The III8XiJmm: allowable concentration of dust with this high percent. of free silioa is £) million partioles per cubic foot for an 8-hour a day exposure. The health h&J:ard associated with silica dust 18 in breathing too high OOMen- trations of the dust. Ballard due to ingesting the dust is DO greater than for 8IIY other dust. In order to obtain SOllllll idea as to the amount of dust in the air d\18 to sources other than the asphalt mix plant, such as street traffic. a semple of air for determiœtion of dust oonoentration was taken up-wind 011 south of the uphalt mix plant. This sample contained O. "" million 1:>81'tioles per 01l1lio foot. This value should be sdJtracted fi'om the dust count Talues made on samples taJœn down-wind or north of the asphalt m1:z: plant to li)ain so- idea of the ooDCentra- tion of dust in the air due to the asphalt m1:z: plant alone. Dust concentration at points in the living and working areas adjacent to the Case and Johnson homes were all below the maximum allowable oonoentraticn. It is quite probQble that, under dif'ferent wind and atmospheric conditioDB. dust coIlØ8ntrations in these areas might be higher or lower than those tb1Ulli on 1;be day of investigation. A health hallard due to dust fi'om the asphalt ai:z: plant did DOt exist on the day of investigation and it is our opinion that a health hazard due to dust from the uphalt mi:z: plant will not exist, under average conditions. How- ever, in our opinion. nuisance conditions due to dust fi'om the asphalt mix plant do exist 8.S evidenced by the gray settled dust on equipment. buildings and TElgeta- tion as well as the dust in evidence in the air. If the asphalt mix plant is to be permanently lcoated at its present site, more efficient dust collecting equip- møn1; should be installed in order to abate this nuisance. . . ~e dust concentration in the working sons of the mixer tender at the asphalt mix plant was about 12 times the maximum allowable concentration, for s\lOh dust. for Sooohour daily exposure. This condition poses a health hazard for the mixer tender even though he may actually work at that particular job aDd pollition only a part of the time. Dust collecting hoods or enclosures should be placed around the mixer and maintained and operated in such a manner as to reduce the dust in the working areas at the plant to below 5 million particles per cubic foot of air. Until such time as this is done, the mi:z:er tender and other workers in the im- mediate area should wear dust respirators. approved by the U. S. Bureau of JI1nes for siliea bearing dust. whenever the plant is in operation. Samples for Acidity and Sulfate. It was the belief' of residents complaining of the air pollution that were being freed from the sulfides no1; removed !'rom the chert by the ing mi1ls and that these gases were being converted to sulfuric acid driven oft of the chert during drying. sulfur gases ore sep81'at- in the moisture Report on IImlstigation ot: Air Pollution, Brown &: Brown Const.

The lowe8t temperature at which pyrite will reloa.o 8ult'ur to form 8ulfur dioxide (S02) under the conditions exi8ting in the plant proceu (oxidizing) i8 3250 Centigrade or 6170 Fahrenheit.

Since the drying temperature \lS8el at the uphalt IIix plant i8 between 2750 and 3000 Io'ahrenheit, it seems unlikely that 8ulfur gaae8 will 'be reloaseel from the small amount8 of sulfide in the chert. It S- S08 ehould be formed in the drying of the chert, it is even leas likely that it would be OOD- wried to sulfurio acid under the ooJlditions existing.

Sinoe oomplain- iDg oitizena believed that sulfuric acid was preseDt in the air and chemicals and equipment 1IØre available for sampling for this substance, two such samples 1IØre taken. The sample taken in the JohDBon flower nursery area shand 118gatiw results for both acidity and. sulfates. A con1;ro1 sample of air was taken in the parld.Dg lot behind the City Hall. This lample was taken to determiœ the acidity and sulfate content of city air not affected by operationa of the aspluù t mix plant. Acidity on this sample was 4.84 milligr81118 per cubic -tor of a1r, expressed aa sulfuric acid. Results tor su1tates 1IØre negative. The negative sulfate result indicates that the acidity found was not due to sulfuric acid. Îhe acidity found in this s8J1Ple can be accounted for by the oø.rbon dioxide content of the air whioh ranges 1'rom 0.025 per cent to 0.05 per cent in normal city air. Result. on these samples indicate that no significant IInO1D1t of sulfurio acid exists in the air adjacent to the Case and Johnson ho_s. Rec 0II1II8 ndations 8 '!'he following reoOlllllSndations are presented for consideration, 1. Installation of more efUcien1; dust collecting equipmøDt at the asphalt mix plant capable of abating the nuisance to surrounding residences. It is suggested that commercial wet type collectors be investigated. 2. Hooding or enclosure of' the mixing equipment at the asphalt plant and collection ot the dust from this source in a manner capable of reducing the dust at the mixer tender's posUien and. the plant site to below 5.0 million particles per cUbic foot of air.

S. Fassnacht Public Health Department Salina, Kansas Dear Sir: With reference to the goat which. you had autopsied at Kansas State College, we found a c~st which contained possibly 500 mI. of thick rl~id attached to the pericardium dorsally on the right atrium of the heart. This cyst extend~d forward into the opening into the thorax and appeared to bring sufficient pressure on vital structures in this region to probably cause the fatal illness and subsequent death of the goat. Advanced age could possibly contribute to the death of the animal, although it could hardly be considered the cause. tJ.cI Very truly yours, > wlk/ek
