(iii)  Treatment does not result in the emission of volatile hazardous waste constituents or toxic air contaminants.

(8)  The hazardous waste treatment is carried out in a quality control or quality assurance laboratory at a facility that is not an offsite hazardous waste facility and the treatment activity otherwise meets the requirements of paragraph (1) of subdivision (a).

(9)  Any waste stream technology combination certified by the department, pursuant to Section 25200.1.5, as suitable for authorization pursuant to this section, that operates pursuant to the conditions imposed on that certification.

(10)  The generator uses any technology that is certified by the department, pursuant to Section 25200.1.5, as effective for the treatment of formaldehyde or glutaraldehyde solutions used in health care facilities that are operated pursuant to the conditions imposed on the certification and which makes the operation appropriate to this tier. The technology may be certified using a pilot certification process until the department adopts regulations pursuant to Section 25200.1.5. This paragraph shall be operative only until April 11, 1996.

(d)  A generator conducting treatment pursuant to subdivision (a) or (c) shall meet all of the following conditions:

The department shall hold at least one public workshop concerning the development of the notification form.

(E)  Any notification submitted pursuant to this paragraph shall supersede any prior notice of intent submitted by the same generator in order to obtain a permit-by-rule under the regulations adopted by the department. This subparagraph does not require the department to refund any fees paid for any application in conjunction with the submission of a notice of intent for a permit-by-rule.

(8)  (A)  Upon terminating operation of any treatment process or unit exempted pursuant to this section, the generator who conducted the treatment shall remove or decontaminate all waste residues, containment system components, soils, and other structures or equipment contaminated with hazardous waste from the unit. The removal of the unit from service shall be conducted in a manner that does both of the following:

(i)  Minimizes the need for further maintenance.

(ii)  Eliminates the escape of hazardous waste, hazardous constituents, leachate, contaminated runoff, or waste decomposition products to the environment after treatment process is no longer in operation.

(B)  Any owner or operator who permanently ceases operation of a treatment process or unit that is conditionally exempted pursuant to this section shall, upon completion of all activities required under this subdivision, provide written notification in person or by certified mail, with return receipt requested, to the department and to one of the following:

The generator shall submit that fee within 30 days of the date that the fee is assessed by the State Board of Equalization, in the manner specified by Section 43152.10 of the Revenue and Taxation Code.

(e)  (1)  Unless otherwise required by federal law, ancillary equipment for a tank or container treating hazardous wastes solely pursuant to this section is not subject to Section 66265.193 of Title 22 of the California Code of Regulations, if the ancillary equipment’s integrity is attested to pursuant to Section 66265.191 of Title 22 of the California Code of Regulations every two years from the date that retrofitting requirements would otherwise apply.

(2)  (A)  The Legislature hereby finds and declares that, in the case of underground, gravity-pressured sewer systems, integrity testing is often not feasible.

(B)  The department shall, by regulation, determine the best feasible leak detection measures which are sufficient to ensure that underground gravity-pressured sewer systems, for which it is not feasible to conduct integrity testing, do not leak.

(C)  If it is not feasible for an operator’s ancillary equipment, or a portion thereof, to undergo integrity testing, the operator shall not be subject to Section 66265.193 of Title 22 of the California Code of Regulations, if the operator implements the best feasible leak detection measures that are determined to be sufficient by the department in those regulations, and those leak detection measures do not reveal any leaks emanating from the operator’s ancillary equipment. Any ancillary equipment found to leak shall be retrofitted by the operator to meet the full secondary containment standards of Section 66265.196 of Title 22 of the California Code of Regulations.

(f)  Nothing in this section shall abridge any authority granted to the department, a unified program agency, or local health officer or local public officer designated pursuant to Section 25180, by any other provision of law to impose any further restrictions or limitations upon facilities subject to this section, that the department, a unified program agency, or local health officer or local public officer designated pursuant to Section 25180, determines to be necessary to protect human health or the environment.

(g)  A generator that would otherwise be subject to this section may contract with the operator of a transportable treatment unit who is operating pursuant to this section to treat the generator’s waste. If treatment of the generator’s waste takes place under such a contract, the generator is not otherwise subject to the requirements of this section, but shall comply with all other requirements of this chapter that apply to generators. The operator of the transportable treatment unit shall comply with all of the applicable requirements of this section and, for purposes of this section, the operator of the transportable treatment unit shall be deemed to be the generator.

(h)  A generator conducting activities which are exempt from this chapter pursuant to Section 66261.7 of Title 22 of the California Code of Regulations, as that section read on January 1, 1993, is not required to comply with this section.

(i)  (1)  Within 30 days of any change in operation which necessitates modifying any of the information submitted in the notification required pursuant to paragraph (7) of subdivision (d), a generator shall submit an amended notification, in person or by certified mail, with return receipt requested, to the department and to one of the following:

(A)  The CUPA, if the generator is under the jurisdiction of a CUPA.

(B)  If the generator is not under the jurisdiction of a CUPA, the notification shall be submitted to the officer or agency authorized, pursuant to subdivision (f) of Section 25404.3, to implement and enforce the requirements of this chapter listed in paragraph (1) of subdivision (c) of Section 25404.

(2)  Each amended notification made pursuant to this subdivision shall be completed, dated, and signed in accordance with the requirements of Section 66270.11 of Title 22 of the California Code of Regulations, as those requirements apply to hazardous waste facilities permit applications.

(j)  A person who submitted a notification to the department pursuant to paragraph (7) of subdivision (d) shall be deemed to be operating pursuant to this section, and, except as provided in Section 25404.5, shall be subject to the fee set forth in subdivision (c) of Section 25205.14 until that person submits a certification that the generator has ceased all treatment activities of hazardous waste streams authorized pursuant to this section in accordance with the requirements of paragraph (8) of subdivision (d). The certification required by this subdivision shall be submitted, in person or by certified mail, with return receipt requested, to the department and to one of the following:

(1)  The CUPA, if the generator is under the jurisdiction of a CUPA.

(2)  If the generator is not under the jurisdiction of a CUPA, the notification shall be submitted to the officer or agency authorized, pursuant to subdivision (f) of Section 25404.3, to implement and enforce the requirements of this chapter listed in paragraph (1) of subdivision (c) of Section 25404.
