NE Well Driller cheat sheet

Nebraska wells are governed by Title 178 NAC 10 (water well construction standards) and Title 178 NAC 12 (licensing of water well contractors and pump installation contractors), administered by the Nebraska Department of Environment and Energy (NDEE).

License classes include water well contractor, pump installation contractor, and individual drillers/pump installers; work must be performed under a licensed contractor, and each well must be reported under the responsible contractor's license number.

Continuing education and license renewal follow a set cycle; a lapsed license bars contracting for new well construction until reinstated, and unlicensed construction is subject to enforcement action.

Construction standards set minimum casing length and diameter, grout type and placement method, annular seal depth, and wellhead termination height above grade to prevent surface water entry.

Grout must be placed by an approved method (e.g., tremie/positive displacement) from the bottom up; free-falling grout or pouring from the top is not acceptable because it bridges and leaves voids.

A well completion report (logging report) is filed with NDEE for each new, deepened, or reconstructed well, recording location, depth, casing, screen, grout, static water level, and formations penetrated.

Abandoned wells must be properly decommissioned by an approved method (filling/sealing the full bore) by a licensed contractor, because open or unsealed wells are a direct conduit for contamination.

Setback distances from contamination sources (septic systems, lagoons, fuel tanks, animal holding areas) are specified in rule; the required separation depends on the source type and must be verified before siting.

Most non-domestic wells in Nebraska must be registered with NDEE; registration creates a record of the well's location, use, capacity, and owner, and is distinct from a permit to appropriate water.

A registration number is issued for each registered well; the number stays with the well/site and must be referenced in reporting and in any transfer of ownership.

New well construction requires registration before or at the time of drilling, with the driller supplying construction details and the owner supplying use and legal description.

Certain uses are exempt from registration, typically small domestic wells serving a single household and specific livestock/limited-use situations; the exemption thresholds are defined in statute and rule.

Changes in well use, ownership, or capacity trigger an update to the registration record; failing to update can complicate water-right administration and property transfer.

Well registration data feed into groundwater management and permitting decisions, so inaccurate reported acreage, use, or capacity can affect the well's recognized status.

Registration is not a water right: in overappropriated or fully appropriated areas, a separate appropriation/transfer process may be required to legally irrigate new acres.

Nebraska's 23 Natural Resources Districts (NRDs) are the local groundwater management entities; a Ground Water Management Area (GWMA) is designated by an NRD where groundwater declines, conflicts, or quality problems exist.

Within a GWMA, the NRD may impose controls such as moratoriums on new well construction, spacing requirements, allocation of annual pumping, metering, and reporting of water use.

NRDs may also designate a Ground Water Quality Management Area or a Phase II/III area where nitrate or other contamination triggers additional requirements such as fertilizer management and certified irrigator training.

The Nebraska Ground Water Management and Protection Act authorizes joint action between NRDs and the state; in fully or overappropriated basins, state and local controls combine.

Overappropriated designations can trigger moratoriums on new uses and require offsets or transfers before new irrigation development is allowed.

Rules differ by NRD and by area phase, so the controlling requirements are the specific NRD's rules and orders, not a single statewide standard.

Water use reporting (flowmeter readings, irrigated acres) is commonly mandatory inside management areas, and noncompliance can result in penalties or loss of allocation.

The federal UIC program (Safe Drinking Water Act) regulates subsurface emplacement of fluids by well injection; Nebraska's UIC program is administered by NDEE under an EPA-approved primacy program.

Wells are classified into classes: Class I (hazardous/non-hazardous industrial and municipal waste), Class II (oil and gas, including disposal and enhanced recovery), Class III (mining/solution), Class IV (hazardous or radioactive waste into or above USDWs, generally banned), Class V (all other injection wells, including many shallow drainage and recharge wells).

Class V wells are often authorized by rule rather than individual permit, but the operator must still meet siting, construction, and inventory requirements and must not endanger underground sources of drinking water (USDWs).

A permit or authorization is required before constructing or operating an injection well; unauthorized injection is a violation enforceable by NDEE and EPA.

Injection must not allow fluid to migrate into a USDW; well construction requires adequate casing, cementing, and injection pressure limits to protect drinking water aquifers.

Mechanical integrity testing, monitoring, and reporting are standard permit conditions for permitted injection wells; records must be retained and submitted as required.

Abandoned injection wells must be plugged and abandoned per approved procedures to prevent cross-connection between aquifers.

Wellhead Protection Areas (WHPAs) are delineated zones around public water system wells where contamination could reach the well; delineation methods include fixed radius, calculated fixed radius, analytical, and numerical modeling.

A WHP program has four core elements: delineation of the WHPA, identification of potential contaminant sources, management of those sources, and contingency planning for alternate water supply.

Nebraska's WHP program is administered through NDEE with local community WHP committees; participation is tied to federal Safe Drinking Water Act source water protection provisions.

Source Water Assessment (SWA) reports identify the susceptibility of each public water system's source to contamination based on contaminant source inventory and aquifer sensitivity.

Potential sources inside a WHPA include septic systems, fuel storage tanks, chemical storage, land application sites, and improperly abandoned wells; these are prioritized for management.

Management approaches are typically non-regulatory (education, land acquisition, best management practices) but may be reinforced by local ordinances such as zoning or source water overlay districts.

Properly constructed and grouted wells and sealing of abandoned wells are primary preventive measures, since a failed annular seal or open borehole bypasses natural aquifer protection.
