Article X of the Nassau County Public Health Ordinance, administered by the Nassau County Department of Health, Bureau of Environmental Engineering, governs development and on-site sewage disposal within designated Special Groundwater Protection Areas (SGPAs). In SGPAs, residential development is limited to one dwelling per 40,000 square feet, and non-residential development is capped at an average daily design sewage rate of no more than 0.00375 gallons per square foot of net area, with industrial wastewater discharge prohibited.
