Accurate classifications of shellfish growing
areas are completed through a comprehensive sanitary
survey. The principal components of the sanitary
survey report include:
1. An evaluation of all actual and potential sources
2. An evaluation of the hydrography of the area,
3. An assessment of water quality.
Complete intensive sanitary surveys are conducted
every 12 years with interim narrative evaluations,
reappraisals, completed on a three-year basis.
Reappraisal reports are less detailed discussions
of the principle components included in the sanitary
surveys. In addition, the reappraisal report does
not require a full shoreline survey. If major
changes to the shoreline or bacterial quality
occur, then the intensive sanitary survey report
is initiated prior to its 12 year schedule. If
only a section of a growing area is either upgraded
or downgraded from its current shellfish classification,
a partial intensive report (Partial Sanitary Survey)
is conducted for that shellfish growing area.
Annual Reviews are written on a yearly basis for
each shellfish growing area.
