3.7.3  

Good site management / practices to avoid / minimise incidences of dust emissions:

Site Boundary and Entrance:

§       Vehicle washing facilities including a high pressure water jet should be provided at every discernible or designated vehicle exit point.

§       The area at which vehicle washing takes place and the section of the road between the washing facilities and the exit point should be paved with concrete, bituminous or hardcore material.

Access Haul Roads and Unpaved Areas:

§       Each and every main haul road should be paved with concrete, bituminous hardcore materials or metal plates, and kept clear of dusty material or

§       Unpaved haul roads and areas should be sprayed with water so as to keep the entire road surface wet.

Excavated Materials:

§       Any stockpile of dusty material should be either: (a) covered entirely by impervious sheeting. (b) placed in an area sheltered on the top and the three side or (c) sprayed with water so as to maintain the entire surface wet.

Exposed Earth:

§       Exposed earth should be properly treated by compaction, hydroseeding, vegetation planting or sealing with latex, vinyl, bitumen within six months of the last construction activity on the part of the site where the exposed earth lie

§       Loading, Unloading or Transfer of Dusty Materials:

§       All dusty materials should be sprayed with water immediately prior to any loading or transfer operation so as to keep the dusty material wet.

Debris Handling:

§       Any debris should be covered entirely by impervious sheeting or stored in a debris collection area sheltered on the top and the three side

§       Before debris is dumped into a chute, water should be sprayed so that it remains wet when it is dumped.

Transport of Dusty Materials:

§       Vehicles used for transporting dusty materials/spoils should be covered with tarpaulin or similar material. The cover should extend over the edges of the sides and tailboard

Site Clearance:

§       The working area for the uprooting of trees, shrubs, or vegetation or the removal of boulders, pole, pillars should be sprayed with water immediately before, during and immediately after the operation so as to maintain the entire surface wet.

§       All demolished items should be covered by impervious sheeting or placed in a spot with shelters on top and three sides within a day of the demolition.

 

 

 

 

 

 

12.1.4

Conduct weekly site audits during construction to ensure that appropriate dust mitigation is being implemented effectively and in accordance with recommendations in the EIA.

Air (Operation Phase)

3.7.12

An odour removal system comprising scrubbers and/or ionizers and/or biofilters should be installed with a minimum combined odour removal efficiency of 95%, with devices used singly or in series. All air ducted from Areas 1 to 5 and Area 6 should be passed through the odour removal system prior to being expelled into the surrounding air.

3.7.13

Good management and operation practice to eliminate odour emissions:

Unloading and Holding Areas of Live Poultry

§       Trucks should be immediately driven to washing area after unloading.

§       All cages and poultry should be sprayed with water immediately prior to unloading in order to eliminate poultry mortality and keep the dusty material wet.

§       High pressure water jet shall be regularly used to spray over the floor surface to keep floor surfaces free from feathers, faeces and other odorous material

Washing Area

§       Empty trucks should be immediately and completely washed by high pressure water jets at designated points before exiting the site.

Slaughtering Plant

§       Floors and equipments in slaughtering and evisceration areas should be cleaned frequently by water spraying;

§       Offal and feathers should be collected and transferred to designated temporary storage area immediately after slaughtering and evisceration processes; and

§       Regular and proper maintenance should be undertaken to ensure ventilation system and equipments operating properly and achieving expected performance

Waste Management and WTF

§       Offal, feathers, dead poultry and other odorous materials shall be stored in refuse bins with close-fitted lid All refuses should be collected by waste collectors and disposed of frequently (e.g. daily);

§       The waste collection frequency should be increased during summer and peak seasons (e.g. twice a day) if necessary;

§       Equipment such as bar screen, containers and tanks should be frequently cleaned to prevent odours from accumulation of organic debris;

§       Screened materials and sludge should be stored in the enclosed containers in order to minimise odour escape; and

§       Sludge, greases and floating solids should be regularly removed in order to prevent putrefaction of accumulated organics in the tank

4.8.1

Good Site Practice:

§       Only well-maintained plant should be operated on site and the plant should be regularly serviced during the construction work

§       Plant used intermittently should be turned off or throttled down when not in use.

§       Plant that is known to emit noise strongly in one direction should be oriented to face away from NSR

§       Silencers, mufflers and enclosures for plant should be used where possible and maintained adequately throughout the work

§       Mobile plant should be sited away from NSR

§       Stockpiles of excavated materials and other structures such as site buildings should be used effectively to screen noise from the work

Use of movable barriers for screening noise from generator, compressor and vibrator. Noise barriers to be used on site should be free of gaps and made of materials having surface mass density of at least 15 kg/m2. Absorptive lining should be adhered on the inner surface of the barrier. The barrier should be in the form of vertical or bend top barrier with an effective height of 3m or above.
