The report on the causes of recent red tides by the University of Hong Kong (“Seeing red over algal blooms”, July 30), highlights the woeful performance of the government in controlling marine pollution.
A major source of pollution is sewage from New Territories houses. Houses constructed under the small-house policy are exempted from building regulations and often have individual septic tanks.
Many village houses are part of large development plans, masterminded by developers and the Heung Yee Kuk, which are a blatant abuse of the small-house policy. Fake farming activities are often used to “condition” land before submitting building applications. Despite often being part of a coordinated development plan, house applications are treated individually. Planning authorities do not assess the cumulative impact of siting numerous septic tanks close to environmentally sensitive waters.
There are no plans to extend mains sewage to most New Territories villages and the government refuses to consider environmentally friendly sewage treatment plants for villages.
The Environmental Protection Department’s guidance material for constructing septic tanks is, by its own admission, incomplete.
The material is way behind international best practice, offering no protection to coastlines other than where there is a gazetted beach. Rules in the Water Pollution Control Ordinance, designed to protect Sites of Special Scientific Interest, mariculture sites and marinas, are ignored. The Lands Department, which processes individual house applications, uses its own document, which was agreed at a secret meeting between the Environmental Protection and Lands departments in 2009. It further waters down the regulations, for instance, removing the need to assess the suitability of soil conditions for septic tanks in many cases.
Monitoring water quality is haphazard and the Agriculture, Fisheries and Conservation Department is incapable of measuring the minute quantities of pesticides which can be extremely toxic to marine life.
The main function of water quality monitoring appears to be to enable the Environmental Protection and Agriculture, Fisheries and Conservation departments to tell everyone that there is no problem. The government lives in a state of denial of serious marine pollution problems.
The unaccountable, incompetent, complacent and uncaring bureaucrats who are in charge of Hong Kong’s environment will not be happy until the land is covered in concrete and the seas filled with plastic, human excrement and chemicals. So much for Hong Kong’s commitment to the Convention on Biodiversity. Compliance is a cosmetic farce.
