(a)
				  By September 1, 2016, and thereafter prior to initial start-up of a newly
				  installed cooling tower, the owner shall obtain or update a maintenance program
				  and plan for each cooling tower, developed in accordance with section 7.2 of
				  Legionellosis: Risk Management for Building Water Systems (
ANSI/ASHRAE
				  188-2015

(b) In addition, the
				  maintenance program and plan shall include the following elements:
(1) a schedule for routine bacteriological
				  culture sampling and analysis to assess microbiological activity at intervals
				  not to exceed 30 days while the cooling tower is in use, and that requires
				  additional bacteriological culture sampling and analysis, as needed, to
				  validate process adjustments;
(2) a
				  schedule for routine Legionella culture sampling and analysis within 14 days of
				  seasonal start-up and, thereafter, at intervals not to exceed 90 days while the
				  cooling tower is in use. Cooling towers in use year-round must sample at
				  intervals not to exceed 90 days, and within two weeks after start-up following
				  maintenance;
(3) in addition to the
				  routine Legionella culture sampling and analysis required by paragraph (2) of
				  this subdivision, conditions that require immediate Legionella culture sampling
				  and analysis, which shall include, but are not limited to:
(i) power failure of sufficient duration to
				  allow for the growth of bacteria;
(ii) loss of biocide treatment of sufficient
				  duration to allow for the growth of bacteria;
(iii) failure of conductivity control, or any
				  other control methods, to maintain proper cycles of concentration;
(iv) a determination by the department or
				  local health department that one or more cases of legionellosis is or may be
				  associated with the cooling tower, based upon epidemiologic data or laboratory
				  testing; and
(v) any other
				  conditions specified by the department or local health department.
(4) provisions requiring immediate
				  and appropriate action, including remedial action, in response to
				  bacteriological and Legionella culture analyses. For Legionella culture
				  analyses, such provisions shall include, but not be limited to, taking all
				  responsive actions required by Appendix 4-A of this Title, including contacting
				  the local health department within 24 hours pursuant to the conditions
				  specified in section 4-1.6  of this Subpart;
(5) provisions requiring that any and all
				  Legionella culture analyses must be performed in accordance with section 4-1.5 
				  of this Subpart;
(6) a shutdown and
				  disinfection plan for removing or permanently discontinuing use of a cooling
				  tower;
(7) provisions requiring
				  treatment and manual or automated flushing of any piping, basin, sump, or
				  wetted surface during idle conditions; and
(8) provisions requiring cleaning and
				  disinfection prior to startup of a stagnant cooling tower that has been shut
				  down without treatment and recirculation for more than five consecutive
				  days.
