The applicable laws and regulations do not provide for variances to the setback requirements, soil percolation requirements, lot size requirements, or other septic system design requirements. The Individual Wastewater Disposal System Regulations at 22 GAR §12105(k) provides for the ability for anyone who is denied a permit to request a hearing before the Guam EPA Board of Directors, which shall affirm, modify, or revoke the denial, or issue the permit on the basis of evidence presented at the hearing. Such request must be filed in writing within 15 days of the official notification of denial by Guam EPA.
