The rules
What a pumper in New Hampshire should know.
A guide, not legal advice. Counties and local health departments can add their own rules on top of the state's, so check with the county where the system is.
- Who regulates septic systemsRun by the state
New Hampshire Department of Environmental Services (NHDES): Subsurface Systems Bureau for septic systems; residuals (sludge and septage) program for haulers. NHDES reviews septic system designs, issues construction and operational approvals after state field inspection, and permits septage haulers, disposal facilities and land application sites; municipalities may also need to approve system plans.
The state program- Pumper and hauler licensingState license
A septage hauler permit from NHDES is required before transporting septage, portable toilet waste or marine sanitation waste over public roads or waters (Env-Wq 1603.01, 1603.03, 1605). One permit is required for each tank, permits run up to two years and expire January 31, and renewals are due at least 15 days before expiration. Tanks must have been inspected by NHDES within the previous two years; vehicles must show the hauler's name, business location and phone number in letters at least 3 inches high, carry the permit and display the permit plate, and carry spill materials for a 25-gallon spill. NHDES inspects septage haulers biennially. Haulers must hold at least one written agreement with a permitted disposal facility or land application site.
Licensing details- Where septage can go
No one may manage or dispose of septage in New Hampshire except at a location holding a permit that allows it, such as a septage site, facility or holding tank permit, a wastewater treatment plant or groundwater discharge permit, or a solid waste facility permit (Env-Wq 1603.01(a)). Land application of domestic septage requires an NHDES site permit (Env-Wq 1608), and septage mixed with portable toilet or marine deodorants or disinfectants may not be land applied (Env-Wq 1607.05).
Disposal rules- Records and reports
Haulers must keep load records (pickup date, client name and address, gallons, receiving facility, discharge date), keep client and destination information in the vehicle, retain records for at least 5 years after the permit expires, and file an annual report by the last business day in January summarizing gallons disposed from each town where septage was pumped (Env-Wq 1605.10, 1605.11). Releases must be reported to NHDES and the local health officer within 24 hours, with an exemption for small contained spills under 25 gallons (Env-Wq 1605.12).
Reporting rules- Inspections
NHDES says lots within 250 feet of waterbodies on the NHDES Consolidated List of Waterbodies require a Waterfront Site Assessment at the time of sale. NHDES field inspectors inspect newly built systems before issuing an Approval for Operation.
