Notes of Decisions

   The failure to use a registered professional engineer with regard to requirements pertaining to plans and specifications under The Clean Streams Law (35 P. S. § §  691.1—691.1001) was not fatally defective to the landowner’s sewage disposal plan, and use of a soil scientist was sufficient. Haycock Township v. Department of Environmental Resources, 530 A.2d 514 (Pa. Cmwlth. 1987); appeal denied 544 A.2d 1343 (Pa. 1988).
