SB550 would strengthen Hawaii’s regulation of municipal solid waste landfills and other waste or disposal facilities to better protect drinking water resources. The bill creates a landfill advisory committee within the Department of Health, chaired by the director of health and including state, county, environmental, and business ներկայացուցիչs, to review and approve or deny applications related to the siting, construction, operation, modification, expansion, or closure of municipal solid waste landfill units.
The bill also prohibits the siting, construction, modification, or expansion of municipal solid waste landfills, construction and demolition landfills, and related components on land that is near or above an aquifer, as determined by the Department of Health in consultation with county water supply officials. It requires the department, working with the Department of Land and Natural Resources and county water agencies, to identify, map, and regularly update maps of all drinking water aquifers in the state and make those maps public. In addition, the bill expands the required buffer zone around waste or disposal facilities from one-half mile to one mile and updates the definition of buffer zone to account for the water table and nearby sensitive uses such as homes, schools, hotels, tourist accommodations, businesses, and hospitals.
SB550 would amend Chapter 342H of the Hawaii Revised Statutes, adding new permitting, siting, and enforcement requirements for landfill and waste facility development. It also authorizes penalties under existing law for violations, including permit suspension or revocation and remediation requirements, and clarifies that the director of health may adopt rules establishing landfill program standards and criteria for determining proximity to aquifers and other sensitive areas. Existing properly permitted facilities may continue operating if they do not expand physically.
The overall sentiment reflected in the bill materials is protective and precautionary, with the bill framed as a drinking-water safeguard and a response to landfill siting concerns near aquifers. The available record does not include committee testimony or recorded votes, so there is no direct evidence of support or opposition from hearings. However, the inclusion of both environmental and business representatives on the advisory committee suggests an attempt to balance environmental protection with operational and economic considerations.
The main points of contention likely involve the stricter siting prohibition, the expanded one-mile buffer zone, and the added approval authority of the advisory committee, all of which could limit where landfills and related facilities may be built or expanded. Counties, landfill operators, and potentially other stakeholders may be concerned about reduced siting flexibility and permitting delays, while environmental and water protection advocates are likely to support the bill’s stronger safeguards for aquifers and drinking water.
SB550 would amend Hawaii Revised Statutes Chapter 342H by adding a landfill advisory committee, expanding the Department of Health’s authority over landfill siting and permitting, and creating new restrictions on waste facility development near aquifers. It would also require statewide aquifer mapping and public access to those maps, broaden buffer-zone requirements, and establish enforcement consequences for violations. The bill would directly affect landfill operators, counties, the Department of Health, the Department of Land and Natural Resources, and county water supply agencies.
The bill’s framing and description indicate a generally supportive, protection-oriented posture focused on safeguarding drinking water and limiting landfill risks near aquifers. No committee transcripts or vote totals are available, so there is no documented floor or hearing debate to measure support or opposition. Based on the text alone, the measure appears to be presented as a public health and environmental protection bill rather than a controversial policy change, though it likely raises implementation concerns for local governments and waste facility operators.
The most notable likely disputes are over the bill’s prohibition on siting or expanding landfills on land near or above aquifers, the increase of the buffer zone from one-half mile to one mile, and the new advisory committee’s authority to approve or deny landfill applications. Counties and landfill operators may view these provisions as restrictive and potentially costly, while environmental advocates and water system officials are likely to support them as necessary to protect drinking water. The requirement to map aquifers statewide and the inclusion of hotel, business, and hospital property lines in the buffer-zone definition may also be contested as expanding regulatory burdens and limiting available landfill sites.
