ENVIRONMENTAL PROTECTION FOR PRODUCTION, COMMERCIAL AND SERVICE ESTABLISHMENTS

Article 18. Wastewater management

1. If any establishment located outside of an industrial zone or an industrial cluster that is not subject to Clause 1 Article 17 hereof operates its wastewater treatment system and has at least a flow volume of 30 m³/day-night, in addition to implementing laws and regulations on wastewater management, it must keep a logbook of operation of this system which is fully compiled and retained for a period of at least 02 years.

The operational logbook must be written in the Vietnamese language, including the following details: flow volume, operational parameters, effluent and influent monitoring results (if any), type and amount of chemicals used, and volume of waste sludge produced, of or from the wastewater treatment system. 

2. If any establishment has a wastewater flow volume of at least 1,000 m³/day-night, in addition to implementing regulations laid down in Clause 1 of this Article, it shall be required to perform the following duties:

a) Automatically and continually oversee and monitor effluent under regulations laid down in Clause 1 and 3 Article 26 hereof;

b) Install a separate digital electricity meter to measure the power consumption of the wastewater treatment system and record all measurement data into the operational logbook;

c) Prepare the plan, infrastructure, vehicles and equipment to respond to and correct system failures or breakdowns that may occur; 

d) Set up a point of inspection and control of discharge of wastewater into the water drainage system installed outside of the perimeter fence which is located along convenient walkways, and have warning signs.

3. If any establishment that generates at least 1,000 m³/day – night within the precincts of an industrial zone or industrial cluster is exempted from connecting to the centralized wastewater collection and treatment system, it shall be obliged to manage wastewater in compliance with Clause 2 of this Article.

4. Where establishments referred to in Clause 1, 2 and 3 of this Article do not autonomously treat non-hazardous wastewater and transfer their wastewater to wastewater treatment establishments that meet environmental technical standards, regulations enshrined in Article 20 hereof shall apply.

Article 19. Management of solid wastes, emissions, noise, vibration, light, heat and radiation

1. Production, commercial and service establishments must carry out management of municipal solid wastes, common industrial solid wastes, biomedical solid wastes and hazardous solid wastes generated from production, commercial and service activities in accordance with laws on solid waste management.

b) Keep an operational logbook of the emission treatment system which is fully compiled and retained for a period of at least 02 years. 

The operational logbook must be written in the Vietnamese language, including the following details: flow volume, operational parameters, amount of water and chemicals used (applicable to any establishment of which form and size is equivalent to establishments that require preparation of an environmental impact statement as defined in the Appendix II to the Decree No. 18/2015/ND-CP); 

c) Carry out automatic and continual monitoring of emissions as stipulated by Clause 2 and 3 Article 26 hereof, and apply for registration as the owner of an emission source as prescribed by laws (applicable to any establishment that releases industrial emissions that belong in the list of high-flow emission sources referred to in the Appendix to the Decree No. 38/2015/ND-CP). 

3. Any establishment creating noise, vibration, light, heat and radiation must invest in and install the system for reducing noise, vibration, light, heat and radiation that meets regulatory environmental technical standards and other relevant regulations.

Article 20. Regulatory environmental protection requirements for transfer of non-hazardous wastewater

1. Establishments transferring non-hazardous wastewater to serve treatment purposes must meet the following requirements:

a) Draw up the plan to transfer, handle and treat wastewater which is specified in the following submissions: the approved environmental impact statement, certified environmental protection proposal, approved detailed environmental protection scheme, certified simplified environmental protection scheme or other equivalents;

b) Apply the same national technical regulations on wastewater as those applied to wastewater receiving and treating establishments;

c) Hold a wastewater treatment contract with wastewater receiving and treating establishments in conformity with requirements set out in Clause 3 of this Article;

d) Build infrastructure facilities used for temporarily storing wastewater provided that these facilities help to prevent spills, overflows and leaks into the surrounding environment.

dd) Permissibly transfer wastewater to wastewater receiving and treating establishments which have signed wastewater treatment contracts agreeing to method of wastewater treatment, and volume of wastewater that is not in excess of the volume specified in the wastewater transfer and treatment plan referred to in Point a of this Clause; 

e) Assume responsibilities for transporting wastewater that fully conforms to regulations laid down in Clause 2 of this Article. Wastewater transfer activities must be fully recorded in the mandatory environmental compliance management report prepared on a periodic basis;

g) Keep a logbook written in the Vietnamese language and retained for a minimum period of 02 years which records details about time, method and volume of transferred wastewater.

2. Wastewater transportation must conform to the following requirements:

a) Transfer wastewater only by drains which are subject to technical regulations on safe design and installation, prevent any spill into the surrounding environment, have valves and flow measurement meters, and are specified in the plan referred to in Point a Clause 1 of this Article, except for the case defined in Point b of this Clause;

b) Carry wastewater generated from drain rinses or hydraulic pressure tests by means of transport, which must conform to the following requirements:

Such means of transport must conform to traffic eligibility requirements as prescribed by laws on transportation, and must be placarded with the sign saying "non-hazardous waste inside" of appropriate size at the front, rear or both sides thereof. 

Storage equipment, holds or compartments must be airtight, watertight, and prevent leakage or corrosion risks from contact with wastewater.

3. Establishments receiving, handling and treating wastewater shall assume the following obligations:

a) Draw up the plan to receive and treat wastewater which is specified in the following submissions: the approved environmental impact statement, certified environmental protection proposal, approved environmental protection scheme, certified simplified environmental protection scheme or other equivalents;

b) Operate the wastewater treatment system built on the suitable technology and having sufficient capacity to treat influent wastewater; 

c) Have the meter to measure the flow volume of wastewater after treatment;

d) Apply the same national technical regulations on wastewater as those applied to wastewater transferring establishments;

dd) Permissibly receive wastewater from wastewater transferring establishments which have signed wastewater treatment contracts agreeing to wastewater treatment method and volume of wastewater which is not in excess of the volume specified in the plan referred to in Point a of this Clause; 

e) Do not transfer received wastewater to another third party for treatment purposes;

g) Keep a logbook written in the Vietnamese language and retained for a minimum period of 02 years which records details about time, method and volume of received wastewater.
