* River water Quality Modeling for Ngoi Dum Stream and Red River:
To estimate the pollutant concentrations in the Ngoi Dum stream and Red River water after
receiving the discharges from WWTP, we used the “River Water Quality Model No.1” (RWQM
No.1) written by International Water Association. The changes of water quality in Ngoi Dum
stream and Red River in case of operation failure are predicted for two scenarios as followings:
- Scenario 1: 4,300 m3/day of untreated wastewater will be discharged directly into the
Ngoi Dum stream in case of operation failure.
- Scenario 2: 9,900 m3/day of untreated wastewater will be discharged directly into the
Ngoi Dum stream in case of operation failure.
The estimated distance from the outlet of WWTP in the Ngoi Dum stream to the confluence with
Red River is of about 2.5 km. Average water flow of Ngoi Dum stream at the downstream section
during the dry season is about 0.6m/s.
The modeling results about water quality trends in the Ngoi Dum downstream following 2
scenarios are represented in the following figures:

stream after receiving untreated waste water from operation failure of WWTP.
The above results show that even for the worst case of WWTP’s operation and whole untreated
wastewater will be directly discharged into the Ngoi Dum stream; the pollutant concentrations will
increase but still meet the allowable standard limits of QCVN 08/2008/BTNMT – class B1. At the
confluence with Red River, the water quality of Ngoi Dum stream for scenario 1 and 2 will vary
from 8.0 to 12.0 mg/l O2 for BOD5; from 3.1 to 3.7 mg/L for total nitrogen; from 0.25 to 0.38
mg/L for total phosphorous; and between 16.6 and 24.1 mg/l O2 for COD (extrapolated results
from BOD), respectively.
Due to water flow of the Red River in the dry season is about 40 times greater than the Ngoi Dum
water flow, the impacts on its water quality is quite low due to its high dilution capacity. The
BOD5 concentrations in the Red River water after receiving and mixing with Ngoi Dum water
when WWTP breakdown taking place could be calculated as following:
Report on Environmental Impact Assessment
Medium Cities Development Project– Lao Cai City Sub-project
____________________________________________________________________________________________
VIWASE – LAVIC Consulting Association
[BOD5]Red River, after mixing = ([BOD5]Ngòi Đum, confluence point + [BOD5]Red River, baseline*39) / 40
Predicted BOD5 concentrations in the Red River after mixing with Ngoi Dum water at the
confluence for Scenario 1 and 2 are:
- For scenario 1: BOD5Scenario 1 = (8 + 2.7*39) / 40 = 2.83 mg/l O2;
- For scenario 2: BOD5Scenario 2 = (12 + 2.7*39) / 40 = 2.94 mg/l O2.
- Similarly, COD concentrations in the Red River after mixing with Ngoi Dum water at the
confluence for scenrios 1 and 2 are:For scenario 1: CODScenario 1 = (16.6 + 5.6*39) / 40
= 5.9 mg/l O2;
- For scenario 2: CODScenario 2 = (24.0 + 5.6*39) / 40 = 6.0 mg/l O2.
To forecast the pollutant dispersion at downstream of Red River, we applied for the most important
parametter, BOD5 as a typical case and assumed that BOD reduction vs time depends totally on
natural BOD decomposition process and ignored all other factors such as adsorption by suspension
particles, flocculation, precipitation/sedimentation, etc.
The variation of BOD concentrations versus time in downstream Red River could be calculated
following the simplified equation (Curi K., 1980):
BODt = BODo *10-kt
In which:
o BODt : is the BOD concentration (in mg/L) at t time units away from the source;
o BODo: is the initial BOD in the river at the confulence point after mixing (mg/L); in
this case BODo is considered as 2.83 for Scenario 1, and 2.94 for Scenario 2.
o t : is the time (day);
o k: is the BOD degradation coefficient; this case k is considered as 0.04 (day-1
).
Because the minimum flow (Vmin) of Red River in the dry season is about 0.5m/s (equally 43.2
km/day), accordingly, the BOD dispersion at different distances towards downstream of Red River
was also simulated as shown in Table 43.

ANNEX 5
Environmental Codes of Practice (ECOPs) for Urban
Construction Projects
The World Bank Operational Policy (OP) on Environmental Assessment (OP 4.01) requires
environmental assessment (EA) of Bank-financed projects to ensure they are environmentally
sound and sustainable. EA is a process of analyzing potential environmental risks and of the
identification and adoption of measures to avoid or mitigate such impacts.
As a part of EA, an Environmental Management Plan (EMP) is a safeguards instrument that is
typically used in many projects and which consists of information on and guidance for the
process of mitigating and managing adverse environmental impacts throughout project
implementation.
Environmental codes of practice (ECOPs) are mitigation measures for generic impacts from
project activities during the construction phase and are intended to be included in the bidding
documents as requirements directed to the construction contractor. ECOPs are not a formally
recognized World Bank safeguards instrument but their use, as part of an EMP, is a convenient
and effective way to ensure that generic and typical construction impacts are adequately
mitigated during project implementation.
If impacts require site-specific mitigation measures that are not adequately covered in these
generic ECOPs, they must be addressed separately in the EMP. These ECOPs also do not cover
impacts from worker camps (assuming they would not generally be needed for small urban
works projects), impacts from large works (bridges, tunnels, big roads). Social impacts caused by
involuntary resettlement or involving ethnic minorities are addressed in other safeguard
instruments. The ECOPs cover dredging operations producing relatively small amounts of
sludge, whilst very large amounts or seriously contaminated sludge would need to be handled
through a separate set of procedures outside of the scope of these ECOPs.
MAIN ENVIRONMENTAL AND SOCIAL ISSUES DURING URBAN WORKS
CONSTRUCTION
Construction activities for small works governed by these ECOPS are those whose impacts are
of limited extent, temporary and reversible, and readily managed with good construction
practices. The environmental and social issues covered in this document are:
Dust generation
Air pollution
Impacts from noise and vibration
Water pollution
Drainage and sedimentation control
Management of stockpiles, quarries, and borrow pits
Solid waste
Chemical and hazardous wastes

MONITORING AND REPORTING REQUIREMENTS
Non-compliance by the contractor could result in suspension of works, financial penalties, or
other penalties, as must be clearly spelled out in the EMP and in the contract.
Contractors are responsible for implementation of ECOPs. The responsibilities for monitoring
ECOPs implementation are typically shared between the contractor, the PMU, and the
Construction Supervision Consultant (CSC) with assistance from the Independent Environmental
Report on Environmental Impact Assessment

Management Consultant (IEMC). The Contractor’s Work Plan should incorporate the guidelines
provided in these ECOPs as well as the Environmental Management Plan (EMP) created for the
sub-project. The designated Technical Officer(s) and Safeguards Officer(s) of the PMUs are
responsible for supervising the adherence to the agreed EMP by the selected contractor(s)
through periodic audits. The World Bank may periodically supervise implementation activities of
Bank-financed projects. The monitoring requirements will differ from project to project and
these are described in the relevant sections of the project EMP.
At a minimum, the contractor should prepare a monthly report on adherence to ECOPs which
should be submitted to the CSC and to the PMU. Project-specific or contract-specific reporting
requirements are described in the EMP. IEMC is responsible for monitoring overall
environmental performance of the project and submit to PMUs quarterly monitoring reports.
