<br />PUBLIC HEARING PROPOSED MERCURY PROCESSING PLANT, PORT PROPERTY. CITY MANAGER REPORT. The City Manager
<br />reported, after reviewing correspondence received from the County Health Department, that it would appear
<br />that if a permit is granted for the operation of this plant, it should be subject to the following restrict -
<br />ions:
<br />1. That an effective collection system be installed, adequate to eliminate all dust and fumes
<br />as a result of the plant's operation, subject to the approval of the County Health Department.
<br />2, That Oddstad Homes agree to reconstruct the plant, if necessary, to comply with any
<br />future legislation, or to meet the requirement of any air pollution district that may be established.
<br />3. That the Plant be under the control of the County Health Department, with the understanding
<br />that operations may be required to cease during periods when prevailing winds or other conditions
<br />may create a nuisance,
<br />The Clerk read the following report submitted by the County Health Department:
<br />In response to your request that the Health Department review and submit comments
<br />regarding potential health hazards and -nuisances that might develop as a result of the
<br />construction and operation of a proposed cinnabar smelting plant at the Port of `
<br />Redwood City, we have reviewed literature and discussed the subject with other agencies
<br />' and wish to submit the following: T'
<br />This department has not seen complete detailed plans for the proposed plant,
<br />therefore it can only comment in a general way upon potential hazards that might possibly
<br />develop. It must be stressed at this point that potential hazards and nuisances due to dust,
<br />fumes and odors are closely associated with the efficiency of the operations and the
<br />maintenance of the equipment installed to control these factors.
<br />Potential points of dust production will be the dumping of ore at a possible stock
<br />piling point, should such operations be proposed; the production of dust in conveying ore
<br />from stock pile to the crusher; dust development in the crusher operation, and at the
<br />roaster operations. It is our understanding that a dust collection system with a
<br />cyclone is to be provided which, it is assumed, will be of adequate capacity to handle
<br />the proposed operation of 40 tons of ore every 24 hours.
<br />The next operation after the roaster, we believe, is the mercury condenser. In this
<br />�.••. operation, the gases are generally scrubbed and vented to the- atmosphere and where sulphur
<br />is concerned in an operation, it is oxidized to S02 and passed into the atmospher. If the
<br />cinnabar is a high quality ore having little gangue material, which might also have a
<br />sulphur content, there would be produced from the handling of 40 tons of ore, 120 pounds
<br />Of S02 per 24 hours. It must be stressed that S02 will also be produced from the sulphur
<br />content of the diesel oil and it has been estimated that approximately 60 pounds per 24 hours'
<br />operation will be produced, using the sulphur content for the average diesel oil. Mr.
<br />Rankin made mo mention of this source of S02 in his calculations.
<br />The City Council is well aware of the fact that at certain periods the atmosphere
<br />in the Redwood City area, more specifically in the Friendly Acres area, does have some
<br />percentage of sulphur derivatives in such concentration that it hd s been known to discolor
