A. 
The economy and desirability of the combined treatment of industrial wastes and sanitary sewage are recognized. It is the intent of these rules and regulations to accommodate the waste disposal needs of industries within the service area of the Authority to the extent that the industrial discharges do not inhibit or interfere with the public sanitary sewage system's intended and required functions, cause physical damage to the structures of the public sanitary sewage system, or cause hazard to those responsible for the operation and maintenance of the public sanitary sewage system or to the general public. In addition, the industrial discharges must be limited in amounts of specific contaminants of a toxic or polluting nature which may pass through the treatment system in objectionable levels as effluent constituents and/or as a residue constituent of the sludge.
B. 
These rules and regulations are intended to provide the basis for this required control and protection of Authority property and responsibility. It should be further understood that the Authority and all industries are subject to the Toxic and Pretreatment Effluent Standards, Section 307 of Public Law 92-500. The federal regulations pertaining to these federal requirements were originally developed by the Federal Environmental Protection Agency (EPA) in 40 CFR Part 126. As of the date of approval of these rules and regulations, EPA is proposing major revisions to its regulations. The EPA regulations on pretreatment standards control the prerogatives of the Authority in the control of industrial discharge, and will always supersede the requirements of these rules and regulations, where discrepancies exist.
A. 
In general, an industrial waste shall be considered harmful to the public sanitary sewage system if it may cause any of the following damaging effects:
(1) 
Chemical retraction either directly or indirectly with the materials of construction of the public sanitary sewage system in such a manner as to impair the strength or durability of any sewerage structures.
(2) 
Mechanical action that will destroy any sewerage structures.
(3) 
Restriction of the hydraulic capacity of any sewerage structures.
(4) 
Restriction of the normal inspection or maintenance of any sewerage structures.
(5) 
Danger to public health and safety.
(6) 
Obnoxious conditions inimical to the public interest.
B. 
All such wastes shall be prohibited from discharge to the public sanitary sewage system.
For all industrial waste constituents which are not compatible with the treatment systems and/or will persist through the treatment systems as a pollutant or toxic substance, pretreatment will be required to the extent the objectionable constituents are reduced to acceptable levels. It is the current intent of EPA to promulgate pretreatment standards for all known toxic and polluting substances, on an industrial classification basis. As these standards are developed, they will become applicable to all industries according to a schedule also to be developed by EPA. It is expected that these will be minimum standards which can be further altered to meet local conditions. Until these pretreatment standards become effective, the prohibition and limits of Article V hereof will govern.
The variability of the rate of discharge from an industrial establishment is an important consideration of the compatibility of the industrial waste with the public sanitary sewage system, and is also subject to regulation. When the variability is considered excessive by Board review or by EPA regulation, the industry shall employ methods and means to reduce the flow rate variability to acceptable levels.
For waste constituents compatible with the public sanitary sewage treatment system and for which the public sanitary sewage treatment system is to provide specific removal capability, the industrial waste shall be subject to surcharge for such constituent concentration in excess of the average influent value upon which the plant design was based. The constituents to which surcharges are applicable include BOD5, suspended solids, ammonia nitrogen, phosphorous, ABS, and oils, fats and greases. The allowable concentrations and surcharge formula are given in Article VII hereof.
A. 
A special industrial waste discharge permit is required for all industrial establishments discharging industrial process waters to the public sanitary sewage system. For all industrial discharges existing as of the date of approval of these rules and regulations, permit application by the discharging industry is required no later than January 1, 1978. No industrial waste discharges from existing industrial connections will be permitted to be made to the public sanitary sewage system after the new treatment plant is placed in operation without a permit from the Board. For all new industrial discharges to be made after the date of approval of these rules and regulations, permit application and approval is required prior to any actual discharge being made to the public sanitary sewage system.
B. 
Each application shall be submitted to the Board and shall contain the following information:
(1) 
Description of process(es) producing the wastes.
(2) 
Description of any pretreatment facilities being or to be utilized.
(3) 
Description of waste being or to be discharged to the public sanitary sewage system in terms of quantity and quality. Complete information of flow variability and chemical/physical/biological constituency is required. Analysis and flow records will also be required for existing installations or for situations where similar installations exist at some other site of the requesting industrial establishment.
C. 
Upon review of the application, the Board will advise the applicant in writing of its approval or disapproval. If disapproval is indicated, full explanation of the reason for disapproval will be given, as will be an opportunity for the applicant to have a hearing before the Board for reconsideration, if so requested by the applicant within 30 days of the Board's notice of disapproval.
D. 
All permits will be granted subject to cancellation by the Board in the event that the industrial discharge becomes adversely different from the conditions upon which approval was originally granted.
E. 
All permittees are required to obtain amended permits for all new or different industrial discharges from those described in the original or last amended permit. All permits are also subject to amendment by the Board in the event that pretreatment requirements of the EPA as originally promulgated or amended differ from the requirements upon which the prevailing permit was based.
F. 
When granted by the Board, all permits will describe in detail the specific monitoring requirements of the discharge(s).
G. 
All new industrial establishments desiring to make physical connection to the public sanitary sewage system shall be required to apply for and obtain a connection permit as described in Article IX, in addition to the industrial waste permit described in this Article IV.
When required by the Board, any person discharging to the public sanitary sewage system any industrial wastes, or industrial wastes and sanitary sewage together, shall install a suitable manhole or manholes or metering chamber on his connecting sewer or sewers to facilitate observation, sampling and measurement of the combined flow or wastes from his premises. Such manhole or manholes or metering chamber shall be accessible and safely located and shall be constructed in accordance with plans approved by the Board or its designated representative. The manhole or manholes or metering chamber shall be installed by such person at his expense and shall be maintained by him so as to be safe and accessible to the Board or its designated representative at all times. The construction and maintenance of such manhole or metering chamber shall be continuously monitored, transmitted and recorded by means of an approved receiving device to be located at the treatment plant.
Although the specific monitoring requirements will be established for each permit at the time of application review, the general guidelines for establishing these requirements, based on the EPA's presently proposed rules for Pretreatment Standards for Existing and New Sources of Pollution, published February 2, 1977 in the Federal Register, are as follows:
A. 
All major contributory industries subject to EPA categorical pretreatment standards shall be required to report quarterly, and minor contributing industries semiannually, on their discharges. For industries not subject to EPA categorical pretreatment standards, reporting requirements will vary depending upon the Board's concern for the potential risk of the discharge. EPA defines the term "categorical pretreatment standard" as any pretreatment standard issued by the EPA Administrator pursuant to Sections 307(b) and (c) of the P.L. 92-500 Act which applies to a particular category or classification of indirect industrial discharges. Major and minor contributing industries will be defined by the EPA in these standards for each industrial category.
B. 
Where reports are required, the initial report shall include analyses based on composite samples for three successive operating days for a minor contributing industry and for each day of an operating week for a major contributing industry. All subsequent reports will be based on composite samples for one operating day during the month preceding the report's required submission.
C. 
A composite sample is considered to be a sample composed of equal parts taken during one-hour intervals during an operating day. All samples shall be taken in a manner and at a location which reasonably characterizes the discharge of the monitored pollutants.
