(a) Advanced age or bad health of applicants;
(b) Relative insignificance of the environmental impact of granting a variance; and
(c) The need of applicants to care for relatives who are aged or incapacitated or have disabilities.
(3) The department shall strive to aid and accommodate the needs of applicants for variances due to hardship.
(4) Variances granted due to hardship may contain conditions such as permits for the life of the applicant, limiting the number of permanent residents using a subsurface sewage disposal system and use of experimental systems for specified periods of time.
