Require control over the quantities and rates of discharge; and/or
(4) 
Require payment to cover the added cost of handling and treating high-strength wastes in accordance with the provisions of Subsection C(15).
If the city requires or permits the pretreatment or flow equalization of waste flows from any industry, the design and installation of the plants and equipment shall be subject to the review and approval of the Engineer and subject to the requirements of all applicable codes, ordinances, laws and regulations of the local, state and federal regulatory agencies.
Where pretreatment or flow-equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense and in such manner that a public nuisance or health hazard does not occur.
When required by the Engineer, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole in the building sewer to facilitate observation, sampling and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located and shall be constructed in accordance with plans approved by the Engineer. The manhole shall be installed by the owner at his expense and shall be maintained by him so as to be safe and accessible to the city at all times.
All measurements, tests and analysis of the characteristics of waters and wastes to which reference is made in this article shall be determined in accordance with the latest edition of Standard Methods for the Examination of Water and Wastewater, published by the American Public Health Association, and shall be determined at the control manhole provided or upon suitable samples taken at said control manhole. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb and property.
A. 
All major contributing industries, as defined in § 94-12 of this article, shall file a weekly report on the constituents and characteristics of the wastewater they are discharging into the municipal system.
B. 
This report shall be compiled from tests taken and analyzed by a certified laboratory. The report shall include the following parameters:

The major contributing industry shall keep daily records of the flows into the municipal system and the condition and maintenance of monitoring equipment.
D. 
Sampling for the above reports shall be by a composite sample taken over the plant workday.
No statement contained in this article shall be construed as preventing any special agreement or arrangement between the city and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the city for treatment, in accordance with § 94-26C(15), subject to equitable payment therefor by the industrial concern.
When wastes of usual or unusual strength of character are accepted, charges to the contributor of the waste will be made by the city in accordance with the following:
A. 
The sewer service charge consists of the normal charge for wastewaters based upon the flow contributed to the sewerage system, plus a surcharge computed on the basis of the concentration of BOD and suspended solids above those established in § 94-26C(15).
B. 
The surcharge described above will be established by computing the pounds of BOD and suspended solids above 400 parts per million and multiplying each by the established city surcharge rate.
C. 
The volume of wastewater flow shall be determined as follows:
(1) 
Whenever the establishment purchases all of its water from the city and discharges nearly all of the water as wastes only to the sewerage system, the volume of water purchased shall be used as a measure of the volume of waste discharged; or whenever the establishment purchases all of its water from the city and discharges substantially smaller part to the sewerage system, an allowance for water not put into the sewer shall be made in computing flow charges. The establishment shall provide, at its own expense, an approved metering facility in order to receive credit for the water not discharged to the sewerage system.
(2) 
Whenever an establishment using a private water supply discharges wastes to the sewerage system, the flow will be based upon the metered use of water used in the establishment or that portion discharging wastes to the system or the metered flow discharged to the sewerage system in the same manner as indicated in Subsection C(1) above.
(3) 
Whenever a mixture of city and privately supplied water is used, the appropriate measurement or combination of measurements described above shall be used.
(4) 
The expense of all wastewater metering facilities shall be borne by the owner of the establishment contributing the wastewater, except for those normally provided by the City of Crisfield for measuring water consumption.
Any person who maliciously, willfully or negligently breaks, damages, destroys, uncovers, defaces or tampers with any structure, appurtenance or equipment which is a part of the sewerage system shall be subject to immediate arrest under charge of disorderly conduct. In addition, the Engineer and other duly authorized employees of the City may institute legal proceedings against such person to recover damages for any losses incurred.
A. 
The Engineer's other duly authorized employees of the City and agents of the Environmental Protection Agency and the State of Maryland bearing proper credentials and identification shall be permitted to enter all properties for the purpose of inspection, observation, measurement, sampling and testing in accordance with the provisions of this article, The Engineer and other duly authorized employees of the City shall have no authority to inquire into any processes, including shellfish preparation and packaging, metallurgical, chemical, oil, ceramic, foodstuffs, paper or other industries, beyond that point having a direct bearing on the kind and source of discharge to the public sewers, waterways or waste treatment facilities.
B. 
The Engineer and other duly authorized employees of the City bearing proper credentials and identification shall be permitted to enter all private properties through which the City holds a duly negotiated easement for the purpose of but not limited to inspection, observation, measurement, sampling, repair and maintenance of any portion of the sewerage system lying within said easement. All entry and subsequent work, if any, on said easement shall be done in full accordance with the terms of the duly negotiated easement pertaining to the private property involved.
C. 
While performing necessary work on private properties, the Engineer or duly authorized employees of the City shall observe all safety rules applicable to the premises established by the owner, and the owner shall be held harmless for injury or death to the City employees, and the City shall indemnify the company against loss or damage to its property by City employees and against liability claims and demands for personal injury or property damage asserted against the company and growing out of the gauging and sampling operation, except as such may be caused by negligence or failure of the company to maintain safe conditions as required in § 94-28.
[Amended 9-12-1979 by Ord. No. 333; 9-12-2001 by Ord. No. 537]
