5.1. Methodology.
5.1.1. Sample collection, handling, and
				preservation techniques specified in 40 CFR §136.3 Table II, or other
				procedures approved by EPA or the Secretary are to be followed.
5.1.1.a. Samples requiring preservation will
				be preserved in accordance with 40 CFR §136.3 Table II for compliance with
				subsection 2.19.1 and the NPDES. All other samples will be preserved in
				accordance with applicable methods and regulations.
5.1.1.b. Sample collection, handling and
				preservation techniques specified by the analytical methods will be followed
				for the parameters analyzed by those methods in the absence of guidance under
				paragraph 5.1.1.a.
5.1.1.c. The
				chain of custody form must be completed at the time of sample collection and
				will state the sampling location, date and time of collection, collector's
				name, type(s) of preservation, number of containers per sample, type of sample
				(grab or composite) and any remarks.
5.1.1.d. After the sample has been collected,
				the appropriate information as to identity of the sample is to be written on
				the label. The identity of the sample must be the same on the label and the
				chain of custody form. The label must remain affixed to the sample container
				and is not to be removed until the required analyses have been completed and
				the surplus sample has been discarded.
5.1.1.e. The chain of custody must accompany
				the sample at all times. Custody of the sample must be documented on the chain
				of custody throughout the life of the sample (from collection to disposal of
				surplus sample after all required analyses have been completed). Any time the
				custody of the sample is transferred from one person to another, except
				analysts in the same laboratory, this transfer must be documented in the
				appropriate fields on the chain of custody form.
5.1.1.f. Immediately upon delivery of the
				sample to the laboratory, the individual delivering the sample will complete
				the appropriate section(s) of the chain of custody form. A chain of custody
				form is not required where the sampler is also the analyst and in situations
				where the laboratory and the sample site(s) are within the property boundaries
				of the facility in which the laboratory is located.
5.1.1.g. Prior to accepting custody of a
				sample, laboratory personnel must be reasonably assured that the sample has met
				the chemical and temperature preservation requirements. If the sample fails to
				meet these requirements, the sample chain of custody form is to be marked
				indicating the sample was improperly preserved. Analytical data resulting from
				improperly preserved samples must be accompanied by a statement indicating the
				condition of the sample upon receipt by the laboratory. Analytical data
				resulting from samples improperly preserved will not be accepted as being in
				compliance with this rule.
5.1.1.h.
				When it is necessary to send samples by mail, bus, courier service, or private
				shipping, the chain of custody form is to be completed by the individual
				relinquishing custody of the sample for shipping and is to accompany the
				samples during shipping. Upon receipt of the samples in the laboratory, the
				provisions of paragraph 5.1.1.g are to be followed.
