## Letters sent to local authorities
The DOE issued directives to all local authorities and District and Land Offices statewide, urging them to step up enforcement against pollution sources.
## Three areas hit unhealthy levels
Nilai recorded an API reading of 172, Seremban hit 168, and Port Dickson reached 155 as of noon, all in the unhealthy range.
## National haze plan activated
All actions related to the haze situation will follow the National Haze Action Plan, with continuous updates to the State Disaster Management Committee.
## Cloud seeding under consideration
NADMA will coordinate potential cloud seeding at the federal level based on current API readings and official guidelines.
## Key takeaway

Negeri Sembilan's DOE is prioritizing ground-level monitoring of open burning while tracking factories, quarries, and vehicles as haze pushes air quality to unhealthy levels.
