<br /> / Appendix A-Exempt Treatment Activities
<br /> There are several treatment activities which,although they would be otherwise regulated,are exempt under the law provided certain conditions are met.
<br /> No notification is required if these are the only treatment activities performed at the facility. These activities are:
<br /> 1.Biotechnology Elementary Neutralization Activities-Refer to HSC§25201.15
<br /> Biotechnology elementary neutralization activities are the elementary neutralization of wastes generated by biotechnology manufacturing or
<br /> biotechnology process development activities. This includes activities conducted in SIC Code Subgroups 283,2833,2834,2835,2836,8731,
<br /> 8732,and 8733,including manufacturing and process development of medicinal chemicals and botanical products,pharmaceutical
<br /> preparations,in vitro and in vivo diagnostic substances,and biological products,and all associated equipment and vessel cleaning and
<br /> maintenance operations. These activities are exempt if ALL of the following conditions are met:
<br /> • A permit is not required to conduct elementary neutralization under federal law.
<br /> • The hazardous wastes are hazardous solely due to acidic or alkaline materials.
<br /> • Either of the following applies with regard to the biotechnology elementary neutralization activity:
<br /> a) The hazardous wastes in the elementary neutralization unit do not contain more than 10 percent by weight acid or alkaline
<br /> constituents.
<br /> b) The generator determines the neutralization process will not raise the temperature of the hazardous wastes to within 10 degrees
<br /> of the boiling point or cause the release of hazardous gaseous emissions.
<br /> The hazardous wastes are not diluted for the sole purpose of meeting the criteria specified in subparagraph(a)above AND after
<br /> neutralization the wastewaters do not exhibit the characteristic of corosivity.
<br /> • The temperature of any unit 100 gallons or larger is automatically monitored,is fitted with a high temperature alarm system,and for
<br /> closed systems,the unit automatically controls the adding and mixing of corrosive and neutralizing solutions.
<br /> 2.Neutralization of Acid/Alkaline Wastes from Regeneration of Ion Exchange Media-Refer to HSC§25201.13(a)
<br /> NO authorization is needed to neutralize acid/alkaline wastes from regeneration of the ion exchange media used to demineralize water,if the
<br /> waste contains less than or equal to 10 percent acid or base by weight.
<br /> 3.Neutralization of Acid/Alkaline Wastes from the Food Processing Industry-Refer to HSC§25201.13(c)
<br /> NO authorization is needed to neutralize add a a 1ne wasre from the food processing industry.
<br /> 4.Silver Recovery-Refer to HSC§25143.13,amended by Senate Bill(SB)2111,(Chapter 309,Statutes of 1998)
<br /> NO authorization is needed for the recovery of silver(provided that the solutions and wastewaters are"silver-only hazardous wastes,and are
<br /> not hazardous for any other reason or constituent)from photofinishing/photoimaging solutions and photoimaging solution wastewaters. These
<br /> wastes are regulated only to the extent they are regulated under the federal Resource Conservation and Recovery Act.
<br /> 5.Sieving or Filtering Under Limited Conditions-Refer to HSC§25123.5(b)(2)(A),amended by Assembly Bill(AB)966,(Chapter 506,Statutes of 1998)
<br /> NO authorization is needed for sieving or filtering Illiquid hazardous waste.tarerlove solid fractions,WITHOUT added heat,chemicals,or
<br /> pressure,as the waste is added to or remove om a storage or accumulation tank orco— ntainer,11 the activity is conducted onsite. For this
<br /> exemption,sieving or filtering does not include adsorption,reverse osmosis,or`utrafiltration.
<br /> 6.Phase Separation Under Limited Conditions-Refer to HSC§25123.5(b)(2)(B),amended by AB 966,(Chapter 506,Statutes of 1998)
<br /> NO authorization is needed for phase separation of hazardous waste during storage or accumulation in tanks or containers,if the separation is
<br /> unaided by the addition of heat or chemicals,and the activity is conducted onsite.
<br /> 7.Combination of Wastestreams Under Limited Conditions-Refer to HSC§25123.5(b)(2)(C),amended by AB 966,(Chapter 506,Statutes of 1998)
<br /> NO authorization is needed for combining two or more waste streams thatAM not incompatible into a single tank or container if the activity is
<br /> conducted onsite and BOTH of the following conditions apply:
<br /> a)The waste streams are being combined solely for the purpose of consolidated accumylaggn or storage or cons ' ated offsite shipment,
<br /> and they are NOT being combined to meet a fuel specification or to otherwiseEe—chemically or physically prepared to be treated,burned for
<br /> enema rgy value,or i9citterated.
<br /> b)The combined waste stream is managed in compliance with the most stringent of the regulatory requirements applicable to each individual
<br /> waste stream.
<br /> 8.Evaporation of Water Under Limited Conditions-Refer to HSC§25123.5(b)(2)(D),amended by AB 966, (Chapter 506,Statutes of 1998)
<br /> NO authorization is needed for evaporation of water from hazardous wastes in tanks or containers,such as breathing and evaporation through
<br /> vents and Floating roofs,WITHOUT the addition of pressure,chemicals,or heat other than sunlight or ambient room lighting or heating,if the
<br /> activity,is conducted onsite.
