A. 
General standards.
(1) 
If the Sewer District permits the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to review of the Sewer District.
(2) 
Grease, oil and sand traps shall be provided when, in the opinion of the Sewer District, they are necessary for the proper handling of liquid wastes containing floatable grease in excessive amounts or any flammable wastes, sand or other harmful ingredients. All such units shall be of a type and capacity acceptable to the Sewer District and shall be located as to be readily and easily accessible for cleaning and inspection. In the maintenance of these units, the owner shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates and means of disposal, which are subject to the review of the Sewer District.
B. 
The Sewer District is not obligated to inspect and review to make recommendations regarding the planning, design, construction, operation or maintenance of pretreatment facilities, and any review or recommendations made by any representatives of the Sewer District is for information purposes only. The Sewer District is indemnified against all loss or damage to the property of the owner of the pretreatment system caused by such review. In no case will recommendations made by the Sewer District relieve the owner in his responsibility to meet any rules or regulations.
C. 
Limitations and pretreatment requirements under this Part 1 shall apply. It is always the responsibility of the user to alert the Sewer District of possible industrial usage or change in use status. The Sewer District may require a user of the sewer services to provide information needed to determine compliance with this Part 1. These requirements may include:
(1) 
Wastewater discharge peak rate and volume over a specified time period and chemical analysis of wastewaters.
(2) 
Information on raw materials, processes and products affecting wastewater volume and quality.
(3) 
Quantity and disposition of specified liquid, sludge, oil, solvent or other materials important to sewer use control.
(4) 
A plot plan of sewers on the user's property showing sewer and pretreatment facility location.
(5) 
Details of wastewater pretreatment facilities and details of systems to prevent and control the losses of materials through spills to the municipal sewer.
D. 
In general, self-monitoring by the publicly or privately owned treatment works or self-monitoring of users mentioned in the discharge permits of these systems is extensively regulated by the federal government, particularly by the United States Environmental Protection Agency regulations on test procedures, allowing only selected standard methods regarding both field sampling and laboratory analytical procedures.
E. 
Sampling. It shall be the responsibility of the owner to ensure that the correct sample container is used, sufficient sample volume is drawn and that samples are composited, recorded and submitted properly to the analytical laboratory, whether private or public.
F. 
Analysis. It shall be the responsibility of the owner to ensure that the laboratory is qualified and the tests are performed in accordance with rules and regulations mentioned in this Part 1 or as amended from time to time.
G. 
Where flow recorders are used, particularly flow recorders that relate flow to only one dimension, such as depth, time or volume, the recorder shall be internally calibrated to ensure proper operation and externally calibrated to actual measurements of depth, time, volume and velocity. Where flow records are required, the recorded data line shall be continuous for the reporting period, clear and readable, with the correct chart size, scale and time duration used.
H. 
Flow measurements and sampling shall be rotated and performed at various times of the day, days of the week and so forth and not simply repetitive so that certain conditions are omitted or only certain conditions selected for representation.
I. 
Samples for analysis and flow measurement will be taken only at control manholes, unless specifically directed otherwise by the Sewer District. The user submitting samples (or data relative to samples) which have been substituted for samples intended to be collected at the control manhole shall indicate and describe the substitution and why it was made.
J. 
The Sewer District may employ or require the user to employ an independent third analytical laboratory to serve as a control, if there are discrepancies between data of the Sewer District and data submitted by such user. The cost for this monitoring shall be borne by such user.
