The Environmental Protection Administration (EPA) yesterday demanded that the coal-fired Ho-Ping Power plant in Hualien County submit additional documents for further environmental review over its request to increase coal imports from Australia.
The agency made the remarks after an Environmental Impact Assessment (EIA) Committee convened earlier in the day to discuss the plant’s plan to import more Australian coal.
The plant has been searching for new sources of coal since a self-imposed ban on coal imports from Russia and Indonesia’s ban on coal exports have reduced the nation’s coal supplies.

The plan to import more Australian coal would be necessary to maintain the plant’s operations, it said.
Over the past decade, Australia exported 42.4 percent of the world’s coal, while 43.4 percent came from Indonesia, 14 percent from Russia and 2 percent from South Africa, the plant said.
The plant requested more flexibility in coal sources to ensure a stable supply of electricity, as coal that produces medium to low levels of the particulate pollutant coal ash is difficult to source.
The plant estimates that the firing process of Australian coal, which contains a high level of coal ash, would lead to a one-third increase of bottom ash and fly ash byproduct.
It requested the coal ash cap be raised from 12 percent to 16 percent, adding that the additional bottom ash and fly ash byproduct would be reused by the nearby Hoping Cement Plant to minimize the environmental impact.
However, EIA committee members stated that as pollutants increase, the plant would need more electricity and vehicles to remove the waste, which would contribute to carbon emissions.
The committee added that it was concerned about the impact of heavy metal contamination on local health and the environment, as the amount of lead and cadmium contained in Australian coal is still not entirely known.
The committee asked the plant to submit a report analyzing the different types of coal and their respective environmental impacts.
To modify an already approved EIA, the plant would need to show that the total amount of pollutants would not increase when using more Australian coal.
If the committee approves the plant’s report, the plan would then need to be accepted by the EPA before being adopted.
The inspection equipment and data transmission system for new robotic dogs that Taipei is planning to use for sidewalk patrols were developed by a Taiwanese company, the city’s New Construction Office said today, dismissing concerns that the China-made robots could pose a security risk. The city is bringing in smart robotic dogs to help with sidewalk inspections, Taipei Deputy Mayor Lee Ssu-chuan (李四川) said on Facebook. Equipped with a panoramic surveillance system, the robots would be able to automatically flag problems and easily navigate narrow sidewalks, making inspections faster and more accurate, Lee said. By collecting more accurate data, they would help Taipei
TAKING STOCK: The USMC is rebuilding a once-abandoned airfield in Palau to support large-scale ground operations as China’s missile range grows, Naval News reported The US Marine Corps (USMC) is considering new sites for stockpiling equipment in the West Pacific to harden military supply chains and enhance mobility across the Indo-Pacific region, US-based Naval News reported on Saturday. The proposed sites in Palau — one of Taiwan’s diplomatic allies — and Australia would enable a “rapid standup of stored equipment within a year” of the program’s approval, the report said, citing documents published by the USMC last month. In Palau, the service is rebuilding a formerly abandoned World War II-era airfield and establishing ancillary structures to support large-scale ground operations “as China’s missile range and magazine
A 72-year-old man in Kaohsiung was sentenced to 40 days in jail after he was found having sex with a 67-year-old woman under a slide in a public park on Sunday afternoon.

A British man was arrested for attempting to smuggle 14.37kg of marijuana into Taiwan through Taiwan Taoyuan International Airport, Taipei Customs said late yesterday. The man, who arrived from Bangkok at 9pm on Friday, was asked by customs officers to open his luggage during a random inspection, Taipei Customs said in a news release. The passenger, whose identity was not disclosed, refused to open his suitcase and tried to flee the restricted area. He was eventually subdued by three customs officials and an Aviation Police Bureau officer. A later search of his checked luggage uncovered 14.37kg of marijuana buds. The case was handed over
