§ 73.2. Scope.
This chapter applies to sewage enforcement officers administering the act, as well as to persons installing individual onlot sewage systems or community onlot sewage systems as defined in [the act] this chapter.
§ 73.3. Policy.
* * * * * (b) When considering corrective measures for malfunctioning sewage disposal systems which have been constructed in accordance with this chapter or applicable regulations at the time of construction, the efforts of the sewage enforcement officer or the Department's staff [shall] will not be restricted by this chapter. It will be the policy of the Department and sewage enforcement officers administering this chapter to first consider all individual onlot and community onlot sewage systems described in this chapter in the correction of existing malfunctions and, when the systems are not physically possible, to provide the best technical guidance possible in attempting to resolve existing pollution or environmental health problems. When application of best technical guidance results in the absorption area or spray field encroaching on the regulated isolation distance to a well, the proper well abandonment procedure or the relocation of the well should be considered. This policy will not limit or preclude the use of experimental systems as provided in §§ 73.71 and 73.72 (relating to experimental sewage systems; and alternate sewage systems) or small flow treatment systems permitted under the Clean Streams Law.
(c) The Department recognizes the existence of technologies related to onlot sewage disposal which are not specifically addressed in this chapter as well as technologies from other disciplines which may be applied to the design or construction of an onlot sewage disposal system. Experimental sewage system permits provide a method for the testing and evaluation of new concepts and technologies applicable to onlot disposal in this Commonwealth. Experimental permits may be limited in number on a Statewide basis. The Department will determine the number of experimental permits that may be issued for a specific experimental technology or design. An experimental onlot sewage disposal system permit shall be required for all technologies, methods, system components, systems and designs the Department deems experimental. Alternate sewage systems provide a classification for innovative and alternative technology which has been developed through the experimental program, by application of existing technologies from other disciplines[,] or through technological advances from other areas of the United States. The alternate sewage system permit will provide a method for utilizing proven technologies within this Commonwealth without constant changes to this chapter. Systems shall be permitted only where it is demonstrated that the proposed system will protect the public health and prevent pollution of the waters of this Commonwealth.

(i) Measurement to the water level in the individual percolation holes shall be made from a fixed reference point and shall continue at the interval determined from paragraph (6) for each individual percolation hole until a minimum of eight readings are completed or until a stabilized rate of drop is obtained whichever occurs first. A stabilized rate of drop [shall mean] means a difference of 1/4 inch or less of drop between the highest and lowest readings of four consecutive readings.
* * * * * (iii) [Where no measurable rate is obtained in a percolation hole, the rate of 240 minutes per inch shall be assigned to that hole for use in calculating the arithmetic average percolation rate.] When the rate of drop in a percolation test is too slow to obtain a measurable rate, the rate of 240 minutes per inch shall be assigned to that hole for use in calculating the arithmetic average percolation rate. When the rate of drop in a percolation test hole using 10 minute intervals is too fast to obtain a measurable rate, that hole shall be considered a failed hole and may not be used in the calculation of the arithmetic average percolation rate.
* * * * * [(8) Acceptance of prior testing results. The sewage enforcement officer may accept the results of percolation tests performed before the effective date of these sections, provided that the tests were observed, conducted or otherwise verified to have been conducted in conformance with the regulations in effect at that time.]
