PART II GENERAL LEGISLATION Chapter 162, SEWERS, ARTICLE VI, Toxic Substances Prohibited or Accepted Conditionally


162-12.  Toxic substances and pathogenic bacteria. 


A.  The following is a partial list of toxic substances and pathogenic bacteria the discharge of which into the Village and county trunk sewer systems or public sewers tributary thereto is hereby prohibited unless their concentration: 

(1)   Is reduced by treatment at the source to a point that will meet the general purposes of these rules and regulations or come within the applicable standards set forth herein under  162-13; or 

(2)   In the opinion of the County Commissioner and Superintendent will not adversely affect any of the biochemical, chemical or other sewage treatment processes: 

(a)  Antibiotics. 

(b)  Arsenic and arsenicals. 

(c)  Bromine, iodine, chlorine. 

(d) Copper and copper salts. 

(e)  Cresols or creosotes. 

(f)  Fluorides. 

(g)  Formaldehyde. 

(h)  Mercury and mercurials. 

(i)   Phenolic compounds. 

(j)   Silver and silver compounds. 

(k)  Sulfonamides, toxic dyes (organic or mineral). 

(l)   Zinc compounds. 

(m) All strong oxidizing agents such as chromates, dichromates, permanganates, peroxides, etc. 

(n)  Chemical compounds producing toxic, flammable or explosive gases, either upon acidification, alkalization, oxidation or reduction. 

(o)  Strong reducing agents such as nitrites, sulphides, sulphites, thiosulphates, etc. 

(p)  Wastes from industrial processes or hospital procedures containing viable pathogenic organisms.     

B.  The above list shall not be deemed to be all inclusive and the County Commissioner or Superintendent may add to or revise the same whenever either one deems it advisable.   


162-13.  Permissible concentrations of toxic substances.


The concentration in sewage of any of the following toxic substances shall not exceed these concentrations judged by the County Commissioner or Superintendent to be toxic to biological sewage treatment processes or to the biota of the receiving waters and shall not exceed the limits specified below when they are discharged to the sewer. These limits may be revised by the County Commissioner or Superintendent whenever in either opinion operating experience so indicates:


 Toxic Substances 

 Permissible Concentration
(milligrams per liter)    



 Chromium Hexavalent 








 Mercuric Chloride 










 Bromide, Iodine, Chlorine 



162-14.  Special concentration limits.


When the volume of a single toxic industrial waste discharge of the combined toxic industrial waste discharge or a group of industries within a single contributary area is so large as to raise a question of the ultimate concentration of toxic substances entering a treatment plant, or in cases where it is known that the toxic substances in the concentrations involved will be effectively removed by the treatment works without causing deleterious effects of any kind to the treatment process, or the receiving waters, the County Commissioner or Superintendent may impose separate or special concentration limits upon the contributors. Conversely, where a toxic industrial waste discharge may be expected to be highly diluted or rendered innocuous before reaching a treatment plant or the receiving waters, the County Commissioner may permit toxic industrial water discharge concentrations greater than those hereinbefore listed provided the higher concentration does not constitute a toxicity hazardous to maintenance workers.
