Land Application Monitoring – All Tiers Land application monitoring shall be conducted by all Dischargers that discharge to land via surface and subsurface discharge methods during the months that a discharge occurs. Hydraulic loading means the rate at which wastewater is applied to the land per unit area. Following wastewater loading, the land shall be rested to provide time to allow soil organisms to biologically decompose organic pollutants in the effluent, organic solids on the ground surface to decompose, and the soil column to reaerate. The duration of the wetting and drying cycles are to document that alternating wetting and resting is occurring.

Septic Tank Monitoring – All Tiers This section’s requirements apply to all Dischargers using a septic tank or tanks as part of their discharge system. All septic tanks at a winery shall be inspected annually to assess accumulated solids and visually assess integrity of the inlet and outlet devices. Measurements shall be made and recorded for the following: Table : Septic Tank Monitoring Parameter Units Sample Type Inspection/ Reporting Frequency
