(1) 
The Town of Hudson Board of Selectmen, hereinafter referred to as the "governing board," desires to establish a Municipal Utility Committee, comprised of seven full members:
(a) 
Two shall:
[1] 
Reside in the Town and reside in a dwelling unit which is serviced by the sewer system established by the Town; or
[2] 
Reside in Town and own real estate which is either so serviced by the sewer system or so situated in a sewer district; and
(b) 
Two shall:
[1] 
Reside in the Town and reside in a dwelling unit served by the water utility; or
[2] 
Reside in the Town and own real estate which is served by the water utility; and

Three shall reside in the Town and may reside in a dwelling or an area not serviced by municipal sewer or water.
(d) 
Additionally, the Committee may have an alternate member, who shall meet the qualification of Subsection A(1)(a)[1] or [2] above.
(2) 
The term of office of each member shall be for three years, appointed on a staggered basis. The governing board shall maintain a separate budget for the sewer utility and shall maintain records of its income and expenditures separate from those of other Town operations. For audit purposes, the sewer utility shall be considered a separate department of the Town operations. Fiscal responsibility and authority for the sewer system shall remain with the governing board;
B. 
The governing board desires to establish a Sewer Capital Assessment Reserve Fund Account, funded by an equitably apportioned assessment to fund capital improvements to the Town's public sewer and sewerage treatment system, with a goal to reduce, if possible, the need to borrow or incur debt for such purposes;
C. 
The governing board desires to establish a separate sewer fund to pay the debt for construction or reconstruction of and to fund the current operating and maintenance costs of the Town's public sewer and sewerage treatment system to be funded by equitably apportioned rents; and
D. 
The governing board desires to establish sewer capital assessment rates and sewer rents for subsequent fiscal years.
A. 
Sewer capital assessment is hereby established effective July 1, 1987, as a one-time special assessment for the connection of a residence, building or other structure, thereafter collectively referred to as a "building or buildings to the Town's public sewer and sewerage treatment system" (referred to Ordinance O-77A, 1982 Hudson Town Meeting, Warrant Article 15 and hereafter referred to as a "system").
B. 
The assessment is fixed according to the formula set forth in Schedule A (on file in the Town Clerk's office). This schedule shall be reviewed and revised by the Municipal Utility Committee on a yearly basis, subject to final review and approval by the governing board.
Sewer rents for use of and/or access to the system are established commencing July 1, 1987, or fiscal year 1988. Sewer rents are to be paid by the owners of buildings and/or land using or connected with the system. Sewer rents are fixed according to the formulas set forth in Schedules B and C. These schedules shall be reviewed and revised by the Municipal Utility Committee on a yearly basis, subject to final review and approval by the Hudson governing board. The schedules shall be filed with the Town Clerk.
A. 
Pursuant to the authority of RSA 149-I:10, there is established a separate and distinct nonlapsing fund known as the "Sewer Capital Assessment Reserve Fund Account." This account shall be reserved to fund construction and reconstruction, replacement, expansion or improvement of the system or for any lawful purpose relating to the sewer system. The Sewer Capital Assessment Reserve Fund Account shall be for the exclusive use of the sewer system.
B. 
Deposit of sewer capital assessments. All sewer capital assessments, paid to the Town, shall be deposited in the Sewer Capital Assessment Reserve Fund Account and shall be used for the purposes reserved for the fund, as designated in Subsection A.
A. 
In accordance with RSA 149-I:10, there is established a separate and distinct nonlapsing fund known as the "Sewer Fund Account." This account shall be reserved to fund management, operation, maintenance and repair or reconstruction of the sewer system, including related bond principal and interest. Any surplus in this fund existing at the end of the fiscal year, as confirmed by the Town's independent audit, shall be used consistent with the lawful purposes to which any surplus may be put, subject to the approval of the governing board.
B. 
Deposit of sewer rents. In accordance with RSA 149-I:10, all sewer rents paid to the Town shall be deposited in a separate Sewer Fund Account and shall be used for the purposes reserved for the fund, as designated in Subsection A above.
C. 
A separate Sewer Utility Checking Account shall be established for all payments made by a Sewer Utility.
A. 
Sewer capital assessment. The Manager and/or Selectmen or their designee shall bill and collect the sewer capital assessment in 12 equal quarterly installments, over a three-year period. Each installment shall be due upon issuance of a bill. If any installment remains unpaid for 30 days after the issuance of a bill, interest shall accrue as established in Subsection C.
B. 
Sewer rents.
(1) 
The Manager and/or Selectmen, or their designee, shall bill in the same month all customer sewer rents on a quarterly basis, starting in July 1, 1992, and every three months thereafter; except that, in order to facilitate a changeover in the billing procedure, for the fiscal year 1992-1993, billing shall be in the third month of each quarter, and in fiscal year 1993-1994, billing shall be in the second month of each quarter. Said billing shall be based upon water usage information furnished by the agency distributing the water to the Town, or some other method, described by the Municipal Utility Committee. In an instance where sewer users have their own source of water supply, an alternate method shall be used by the Sewer Utility to calculate the bill. If any bill remains unpaid after 30 days of the date of issuance, interest shall accrue as established in Subsection C.
(2) 
The Municipal Utility Committee shall draft for review and approval by the governing board the information and format which appears on the sewer utility bill. All sewer utility charges shall be fully substantiated by the governing board before being submitted to the Municipal Utility Committee for billing, as they are related to the sewer utility budget.
C. 
Interest. Interest shall be assessed in accordance with RSA 76:13, or successor statute as permitted by law.
A. 
As provided in RSA 149-I:11, the sewer capital assessment and sewer rents shall create a lien on the real estate against which they are assessed, and, to enforce collection of the liens, the Manager and/or Selectmen or their designee are authorized to use all procedures provided by law, including those set forth in RSA 38:22 and RSA 80, and to issue a warrant, or other appropriate process, to the Tax Collector.
B. 
Upon the Town's approval of an application for a building to connect with and discharge into the system, as provided in § 270-3 above, the Manager and/or Selectmen or their designee shall cause to be recorded with the Hillsborough County Registry of Deeds a notice of sewer capital assessment, which notice shall be on a form prepared by the Manager and/or Selectmen and shall include, as a minimum, the names of the property owners, addresses of the property owners, names of the applicants for the sewer system connection, address of the property, amount of sewer capital assessment, or delinquent rents, and due date for payment of same.
A.

The Superintendent may, at his/her discretion, reallocate industrial loadings, establish mass-based discharge limits, adjust present discharge limits and establish new limits to meet the needs of the wastewater facility or collection system.
E. 
Federal regulatory provisions applicable to this section are 40 CFR 403.5(a), General prohibitions, 40 CFR 403.5(b), Specific prohibitions, and 40 CFR 403.5(c) and (d), regarding local limits development.
A. 
Basis for imposing new sewer allocation limitations.
(1) 
Pursuant to Hudson Town Code (HTC) § 270-14, the Town of Hudson entered into an intermunicipal agreement with the City of Nashua for the purpose of providing wastewater treatment services to the Town of Hudson. The agreement provides the Town of Hudson 2,000,000 gallons per day of secondary wastewater treatment;
(2) 
The Town of Hudson is presently undertaking a study as part of its Sewer Master Plan to evaluate methods to reduce infiltration and inflow into the Town of Hudson's wastewater treatment system that may result in an increase in available sewer capacity;
(3) 
The Town of Hudson wastewater treatment system is presently distributed within an area described in the attached Exhibit A, Town of Hudson Sewer Master Plan Amendment System Boundary and Nonsewered Parcels. Before the Town of Hudson undertakes an expansion of its wastewater treatment system beyond the existing system boundary, the Town must first provide sewer to all land uses within the presently serviced region and then the Town can plan for possible expansion of the wastewater treatment system to those areas outside of the presently serviced area as described in Exhibit A; and
(4) 
In November of 1999 the Town of Hudson Board of Selectmen adopted a Master Plan Amendment for the Town of Hudson Sewer Master Plan. That Master Plan Amendment indicated that there presently remain approximately 200,000 gallons of average daily flow available within the per-day limit of 2,000,000 gallons established by the intermunicipal agreement with the City of Nashua. Therefore, in order to protect the public health, safety and welfare of the Town of Hudson and to fairly allocate the remaining sewer capacity among the land uses permitted under the Hudson Zoning Ordinance, the Board of Selectmen must implement new procedures for making sewer allocations to new and existing land uses within the Town of Hudson.
(5) 
Now, therefore, the Board of Selectmen adopts the following new regulations with regards to the allocation of the remaining sewer capacity presently available to the Town of Hudson under its current agreement with the City of Nashua.
B. 
Method for allocation of remaining sewer capacity.
(1) 
In furtherance of the new policy of allocation, the Board of Selectmen establishes the following standards to be implemented for the allocation of municipal sewer capacity. Except as provided in this subsection, the Board of Selectmen will not approve new sewer allocations from the remaining sewer capacity for any use located outside of the system boundary as described in Exhibit A; provided, however, that the Selectmen may, in their sole discretion, grant a request to deliver sewer outside the existing system boundary described in Exhibit A for public facility uses, such as schools and other governmental uses, for community facilities, such as hospitals and public utilities, or for other residential, commercial or industrial uses that in the opinion of the Board of Selectmen are essential for the public health, safety and welfare of the Town of Hudson.
(2) 
Residential uses: flow allocation.
(a) 
Allocation of sewer for residential uses will be done on a per-acre basis as described in the following allocation table for residential uses.
(b) 
The allocation table herein will exclude lands that contain slopes in excess of 25%, wetlands, noncontiguous dry land and all lands dedicated to public or private rights-of-way.
(c) 
To determine the density for residential development, first determine the total acreage of the development parcel, subtract nonbuildable lands as described in Subsection B(2)(b) above and then multiply the remaining acreage by the average daily flow available for the parcel and then use the per-unit flows for the type of unit desired to establish density.

C. 
Exemptions to new allocation system.
(1) 
All land uses:
(a) 
Subdivisions or site plans for uses that were in conformity with RSA 674:39 on August 17, 1999, will be exempt from the allocation limitations embodied in this chapter. The subdivision or site plan must have been approved by the Hudson Planning Board and must have been recorded at the Hillsborough County Registry of Deeds and must have commenced active and substantial construction at the project site within one year of the date of approval and must have completed substantial improvements within four years of the date of approval and recording at the Registry of Deeds; or still be within the four-year period of exemption pursuant to RSA 674:39 after commencement of substantial improvements. In addition, the subdivision or site plan must remain in full compliance with all Planning Board terms and conditions of approval and not require Planning Board approval for a substantially modified subdivision or site plan; and
(b) 
The subdivision or site plan shall demonstrate compliance with Hudson Town Code § 289-41 as of August 17, 1999, Subdivision Regulations. The subdivision or site plan must still be valid pursuant to HTC § 289-41 as of August 17, 1999, and, the necessary steps pursuant to HTC § 289-41 must have been undertaken thereafter to have the plan recorded before the one year expires. In addition, the subdivision or site plan must remain in full compliance with all Planning Board terms and conditions of approval and not require Planning Board approval for a substantially modified subdivision or site plan.
(2) 
Industrial uses. Notwithstanding the foregoing Subsection C(1)(a) and (b), industrial uses will be entitled to the following additional exemption to the allocation policy. Existing industries that have anticipated expansion and that have submitted industrial discharge permit applications for such expansions of use and have submitted a request for additional sewer allocation prior to December 31, 1999, will be evaluated on a case-by-case basis, by the Town Engineer and Sewer Consultant, with a final decision on additional allocation of sewer to be made by the Board of Selectmen.
(3) 
Periodic review. On an annual basis, the Town Sewer Consultant and/or the Town Engineer shall determine whether or not improvement in the inflow/infiltration problem has made available additional sewer capacity. At such time, the Sewer Consultant and/or the Town Engineer may make recommendations to the Board of Selectmen to increase or modify the amount of sewer allocation to be made available to residential and retail and service/community facilities/industrial/agricultural uses as described in the charts contained in Subsection B. In addition, the Town shall continue to undertake efforts to negotiate for additional sewer capacity from the City of Nashua.
D. 
Procedure for making new sewer allocations.
(1) 
All requests for new sewer allocations must submitted to the Town Engineer. All requests will be reviewed by the Town Engineer and, when necessary, by the Sewer Consultant. After review by the Town Engineer, and Sewer Consultant where appropriate, the Hudson Board of Selectmen will act upon allocation requests. Final action on an allocation request can be:
(a) 
Denial (with reasons);
(b) 
Approval (with reduction of request);
(c) 
Flow approval (with stipulations); or
(d) 
Approval as applied for.
(2) 
Allocation expiration. All new sewer allocations issued by the Board of Selectmen pursuant to this section will be void within 90 days from issuance unless within that period of time a subdivision or site plan application for the same use described in the sewer allocation request has been accepted by the Planning Board as a completed application pursuant to RSA 676:4. Furthermore, all new sewer applications will expire for any approved subdivision or site plan if any subdivision or site plan becomes invalid pursuant to HTC § 289-41.
E. 
Existing buildable lots of record. Existing buildable lots of record as provided under the Hudson Zoning Ordinance that are not in the Town Residence Zone and which are less than one acre in size will be allocated the following sewer flow allocations:
(1) 
Residential:
(a) 
Buildable land, less than one acre: 250 gpd.
(2) 
Commercial, industrial and other parcels:
(a) 
Buildable land, less than 1/2 acre: 500 gpd.
(b) 
Buildable land, less than one acre: 1,000 gpd.
F. 
Industrial discharge agreement review and repurchase. Each industrial user that has an existing industrial discharge agreement will be subject to an annual review of that industrial discharge agreement for the purpose of identifying whether or not the industrial user is making use of all allocated flow. The Town reserves the right to purchase unused allocation so long as the Town makes the suitable payment back to the industrial user of the previously paid capital assessment fee. The decision by the Town to purchase sewer allocation provided under an existing industrial discharge agreement must be based upon some reasonable public health, safety and welfare judgment of the Town of Hudson acting through the Town Engineer and the Sewer Consultant, with all final decisions to be made by the Board of Selectmen.
G. 
Private improvements to sewer infiltration/inflow. Upon request by an existing or new sewer user, the Board of Selectmen will consider proposals for making capital improvements to part or all of the wastewater treatment system to improve the inflow/infiltration problems. Such proposals shall be in the form of detailed engineering designs and drawings describing the construction of such improvements. After review and consultation with the Sewer Consultant and the Town Engineer, the Board of Selectmen may, in its sole discretion, approve specific projects wholly funded and undertaken by new or existing sewer users. Upon completion of those improvements, the Board of Selectmen is authorized to allocate to the project proponent such portion of any recovered sewer capacity as may be mutually agreed to between the Board of Selectmen and the project proponent, so long as the amount of recovered sewer capacity is demonstrated to exist according to reasonable engineering principles as confirmed by measurement by the Town Engineer or Sewer Consultant.
