503.4 Quantity of supply.
(a) Quantity of supply.
Every water corporation will file with the department a copy of its emergency plan for maintaining a reasonable supply of water during a drought or other emergency affecting the maintenance and delivery of a safe and adequate supply of potable water. A water corporation may submit a copy of the plan filed with and approved by the State Department of Health pursuant to 10 NYCRR 5-1.33. The plan will include provisions for implementing water use restrictions and other conservation measures and for utilizing alternate and existing or potential emergency supplies.
(b) Surface sources.
Each water corporation that employs a surface source of supply shall comply with the provisions of the Ten State Standards, with the additional requirement that the maximum projected demand shall take into consideration forecasted growth or decline in both the number of customers and in system usage for at least a 10-year period into the future. Also, such projections shall be updated on an ongoing basis and where they show that demand will exceed supply, the water corporation shall undertake all reasonable efforts to reduce and control future demands to bring them into balance with supply. If appropriate, the water corporation shall develop plans, consistent with existing State requirements, to secure additional supply.
(c) Groundwater sources.
Each water corporation that employs groundwater sources of supply shall comply with the appropriate provisions of the Ten State Standards with the additional requirement that the numbers used for design average and maximum day demand shall reflect a projection of growth or decline in the number of customers and in system usage for at least a 10-year period into the future. Also, such projections shall be updated on an ongoing basis and where they show that demand will exceed supply the water corporation shall begin measures to control demand or, if appropriate, secure additional supply.
(d) Monitoring requirements.
(1) Surface sources.
Each water corporation shall submit to the department for approval as soon as possible, but no later than one year after the effective date of these standards, a plan to monitor source capacity and establish warning levels for declining source capacity. The plan's warning levels should be based upon original design demand and historical source levels so as to provide a warning when the source capacity falls below design capacity. Once the plan is implemented, which must occur no later than two years after the effective date of these standards, daily records shall be kept indicating source level or capacity, date, and location of reading for each source. The department shall be notified within one business day whenever the source level falls below the established warning levels.
(2) Groundwater sources.
Each water corporation having a groundwater source shall equip each of its well pumps with a timing device which indicates time operated on a 24-hour basis. Each company shall have the resources to meter the discharge of each well under normal operating conditions. Readings shall be taken and recorded on a daily basis and shall indicate the discharge of each well or group of wells on a common discharge line, time of operation, well identification, date and time of day recorded. The chart produced by an automatic flow recording device shall be sufficient to satisfy this requirement. For the purposes of this rule, a group of wells from which water is withdrawn by a common source of suction shall be considered a single well. Production meters shall be calibrated every two years. At least once every three years each water corporation will conduct tests to determine the specific capacity of each well authorized for use and the actual capacity of each well's pump. As used in this Part, specific capacity shall refer to the yield of a well in gallons per minute per foot of drawdown. The results of these tests will be reported to the department within 10 business days if the specific capacity results indicate a 10 percent or greater decrease in specific capacity as compared with rated specific capacity or if the well pump capacity is less than 80 percent of the design rated capacity. The rated specific capacity of each source will be reported to this department within three months of enactment of these standards. Any changes in rated specific capacity of any source must be reported to this department within 10 business days.
(3) Additional monitoring requirements - total production.
The average day design demand and maximum day design demand will be reported to this department within three months of enactment of these standards. The department will also be notified whenever:
(i) actual maximum day production exceeds maximum day design demand; or
(ii) actual average day production exceeds average day design demand on an annual basis.
