Current through Register Vol. 50, No. 6, June 20, 2024
A. This
				item will be satisfied when the following requirements are met.
1. Before an area is classified as approved,
				conditionally approved, or restricted, a sanitary survey shall be completed.
				The survey is a report completed prior to allowing harvesting from the
				area.
2. Each sanitary survey
				report shall identify and evaluate all actual and potential sources of
				pollution which may affect the growing area; determine the distance of such
				sources to the growing area; assess the effectiveness and reliability of sewage
				treatment systems; and ascertain the presence of poisonous or deleterious
				substances, e.g., industrial, and agricultural wastes, pesticides or
				radionuclides. The presence and location of small sources of pollution such as
				boats which might contribute direct fresh fecal matter and poisonous or
				deleterious substances to the area shall be evaluated. The presence of
				domestic, wild animal, or migrating bird populations shall be considered for
				possible adverse effects upon water quality. Offshore growing areas located in
				the vicinity of ocean dump sites shall be evaluated for biological and chemical
				wastes and radiological materials. Other environmental health factors that may
				affect the quality of the shellfish resources should also be evaluated in the
				sanitary survey report.
3. Each
				sanitary survey report shall evaluate any meteorological and hydrodynamic
				effects and geographic characteristics that may affect the distribution of
				pollutants over the growing area. These factors shall be assessed to determine
				their maximum effect on water quality.
4. Each sanitary survey report shall include
				the collection of growing area water samples and their analysis for
				bacteriological quality. The number and location of sampling stations selected
				shall be adequate to produce the data necessary to effectively evaluate all
				point and non-point pollution sources. Recommended that sampling stations shall
				be established to evaluate all freshwater discharges into the growing area. The
				collection of samples shall form a profile reflecting adverse meteorological,
				hydrographic, seasonal, and point source, and geographic pollution conditions
				to assure the requirements for classifying growing areas as approved (§109),
				conditionally approved (§111), or restricted (§113) are met.
5. The sanitary survey shall be maintained on
				an annual basis in order to assure that data is current and sanitary conditions
				are unchanged. If actual or potential pollution sources impact upon the area,
				it is necessary to annually update sanitary survey data including the field
				review of pollution sources and the collection of at least five water quality
				samples from each stations selected to accurately represent shellfish
				sanitation in the area under consideration.
6. The sanitary survey shall be reviewed and
				the growing area classification reevaluated at least every three years to
				assure the accurate classification of each growing area. The reevaluation shall
				include, at a minimum, an examination of the Oyster Water Monitoring Program's
				bacteriological database of at least the last five prior years. The minimum
				number of samples required within the five-year database is 15. For a
				harvesting area to be classified as approved, the requirements of
				§109 must be met. For a harvesting area to
				be classified as conditionally approved, the requirement of
				§111 must be met. For an area to be
				classified as restricted, the requirements of
				§113 shall be met.
7. A report shall be prepared for each
				sanitary survey and each reevaluation. Reports shall contain an analysis of the
				sanitary survey data, and a determination that the area classification conforms
				with the applicable criteria.
8.
				Areas classified as approved, conditionally approved, or restricted that do not
				comply with the sanitary requirements of the designated classification shall be
				immediately reclassified to the appropriate category.
9. The central sanitary survey file shall
				contain all information related to the classification of each area including
				sanitary survey reports, updated sanitary survey data, and reevaluation
				reports.
