5 The MANUAL has been prepared as a guide to those persons responsible for the discharge of treatedwastewater to waters of the Commonwealth and for the construction of sewers, pump stations andtreatment FACILITIES . Parts I and II briefly set forth information regarding the responsibility and thefunctions of the Department of Environmental Protection (Department) in carrying out the policies andprovisions of the Clean Streams Law and the procedure for obtaining permits for discharge and for theconstruction and operation of treatment Department s policy for conducting technical reviews and approvals of permit applications containedin DEP document #362-2000-007 is applicable to this MANUAL .

6 The policy states that the Department willconsider the registered professional engineer whose seal is affixed to facility design documents to be fullyresponsible for the adequacy of all aspects of the facility design and compliance with the state standardsand requirements. The Department approval or issuance of permit does not, in any way, relieve the designengineer of this III is a detailed technical guide for consultants and sanitary engineers, containing minimumrequirements and limiting factors used by the Bureau of Water Quality Protection in the review ofapplications for treatment FACILITIES permits. It has been based primarily on the Recommended Ten StatesStandards for WASTEWATER FACILITIES adopted by the Great Lakes and Upper Mississippi River Board ofState Public Health and Environmental design of WASTEWATER FACILITIES should not be limited by minimum requirements, but must meet theneeds of the particular situation.

7 It is not the purpose of this MANUAL to set forth data which can be usedwithout due regard for the requirements of the particular project under design. The judgment of the skilledprofessional engineer is still required to apply these data. The Department will apply more stringent criteriawhen, in its judgment, their use is justified. With the foregoing qualifications definitely understood, theDepartment considers the items set forth in Part III of this MANUAL as generally representative of goodengineering processes and variations of processes are proposed from time to time. Lack of description or criteriafor a process does not suggest a process should not be used, but only that consideration by the Departmentwill be on the basis of information submitted with a specific design.

8 The MANUAL explains the requirementsfor experimental processes in Section , entitled Applications for New Processes . Data on newlyproven processes are usually meager, and final standards cannot be adopted immediately or included in arevised MANUAL . Tentative standards for such processes will be available as information is submitted andreviewed. The Department reserves the right to amend this MANUAL if and when necessary to incorporatesuch new processes.
