Noise pollution<br />
• Adverse<br />
• Long term<br />
• Low occurrence<br />
• Minor significance<br />
• Medium<br />
risk<br />
• The residents near RAH-STP<br />
may experience high noise levels<br />
if the pumps and motors used in<br />
the STP are not properly<br />
maintained.<br />
The recommended additional mitigation measures for reducing the environmental risk<br />
levels and improving the environmental performance are listed below against each of<br />
the environmental specifications of <strong>PDO</strong>, viz., SP-1005 to SP-1012 and SP-1170.<br />
Specification<br />
SP-1005: Specification for<br />
Emissions to Atmosphere<br />
SP-1006: Specification for<br />
Aqueous Effluents<br />
SP-1007: Specification for<br />
Accidental Releases to<br />
Land and Water<br />
SP-1008: Specification for<br />
Use of Energy, Materials<br />
and Resources<br />
SP-1009: Specification for<br />
Waste Management<br />
SP-1010: Specification for<br />
Environmental Noise and<br />
Vibration<br />
Areas of Non-compliance or<br />
Concern<br />
• Transboundary emissions from<br />
vehicular traffic on Qurum<br />
Heights highway, stack emissions<br />
from ORC and fugitive emissions<br />
from SMOC, BPO and offshore<br />
facilities have significant affect<br />
on the areas serviced by estate<br />
services and the surrounding<br />
residential areas.<br />
• Treated effluent from MAF-STP<br />
showed repeated non-compliance<br />
with respect to ammoniacal<br />
nitrogen and free chlorine.<br />
• STP monitoring is not<br />
comprehensive and some critical<br />
parameters such as heavy metals,<br />
phenols, sodium absorption ratios<br />
etc. are not monitored.<br />
• STP monitoring frequency is not<br />
adequate. Weekly monitoring<br />
cannot detect if standards are<br />
breached during peak load times.<br />
• The application of Standard A-2<br />
for treated sewage quality is<br />
questionable since the irrigated<br />
areas are accessible to public.<br />
Application Standard A-1 will<br />
lead to repeated non-compliance.<br />
• None<br />
• Per-capita domestic water<br />
consumption in RAH remains<br />
quite high.<br />
• Total water consumption in MAF<br />
and RAH shows steady increase<br />
over the years.<br />
• None<br />
• Residents near RAH-STP may<br />
experience high noise levels if the<br />
pumps and motors used in the<br />
STP are not properly maintained.<br />
Recommended Additional<br />
Mitigation Measures<br />
• Track the air emission<br />
inventories and air quality in<br />
the airshed<br />
• STP performance and<br />
operating practices shall be<br />
reviewed.<br />
• Critical parameters such as<br />
heavy metals, phenols,<br />
sodium absorption ratios etc.<br />
shall be monitored at least on<br />
quarterly basis.<br />
• Monitoring frequency may<br />
be increased to four times<br />
per day for on-site<br />
measurements and composite<br />
samples may be taken for<br />
laboratory analysis<br />
• The issue relating to the<br />
application of Standard A-2<br />
needs to be resolved, in<br />
consultation with<br />
MRME&WR.<br />
• None<br />
• Water conservation shall be<br />
promoted in the <strong>PDO</strong><br />
accommodation facilities.<br />
• None<br />
• Through periodic noise<br />
monitoring, compliance with<br />
source and ambient noise<br />
standards shall be ensured.<br />
