EnviroRisk International Inc.

EnviroRisk has a long history of engaging with Saudi Electricity Company (SEC) in support of environmental studies. We have conducted many environmental impact assessment and environmental review studies for Power Plants across the Kingdom. Our team has helped to assess the potential environmental impacts caused by Power Plant expansions (e.g.,Shoiabah & Rabigh Power Plant) and proposed cost-effective mitigation measures and environmental management plans to reduce environmental pollution.

Through the undertaking of periodic environmental reviews for SEC Power Plants, our team of consultants assessed various environmental issues (e.g., air emission, noise, groundwater, waste, and wastewater) during Power Plant operation and the status of regulatory compliance.

In 2009, EnviroRisk prepared Environmental Impact Assessment Report for the Concept Master Plan of Jizan Economic City (JEC), an economic city in the Jizan Province of the Kingdom of Saudi Arabia, with a focus on the energy and manufacturing industries. In 2012, we conducted Environmental Impact Assessment for City Design Update.

Our technical team evaluated the impacts of original and updated design through comprehensive environmental assessments for various aspects including air, noise, water and groundwater quality, flood, traffic, marine, etc. Our technical team has utilized various modeling tools for regional air quality impact assessment, runoff assessment, flood risk assessment, sediment transport, and traffic prediction, etc. 

 

Noise and vibration are major environmental concerns associated with railway operation. EnviroRisk was invited to undertake a comprehensive noise and vibration assessment for a rail transit system in the Kingdom.

Through the application of state-of-the-art modeling techniques, our team assessed the noise and vibration propagation from the proposed railway system under different transit railway station design and operation scenarios.  Our modeling study also evaluated the performance of sound barriers for noise attenuation and identified the required height and installing locations for noise barriers to effectively limit the levels of noise entering the residential communities adjacent to the railway.

The rapid urban growth, as well as the subsequent increase in industrial activities and traffic congestion, have resulted in significant deterioration of urban air quality. Environmental regulatory in the Kingdom has planned to expand the existing air quality monitoring network. 

One major concern is to identify the suitable locations where the new monitoring stations should be placed to maximize the value of these new stations. EnviorRisk performed regional air quality modeling studies for many cities in the Kingdom to identify the optimum locations for placing new air quality monitoring stations. 

In 2013, Saudi Arabian Oil Company (Saudi Aramco) proposed to upgrade the existing diesel and gasoline product specifications for sulfur, benzene and aromatics at Ras Tanura Refinery (RTR) under the ‘Clean Fuel and Aromatics (CF&A) Project. After an EIA for the CF&A project was prepared, SaudiAramco decided the modify the scope of the project by modifying the production of some chemical species (e.g., Benzene, Toluene) and associated storage and exporting facilities. As a result, the emission inventory prepared for previous RTR Clean Fuel & Aromatics project has to be updated.

Our team re-evaluated the emission inventory for RTR caused by the installation of new combustion units, modification of design capacity, and removal of chemical storage and handling facilities. The updated emission inventory comprises an estimation of emissions from process stacks, new flare systems, new process heaters, sulfur recovery units, vapor recovery units, gasoline blending tanks, as well as over 100 new and refurbished diesel and gasoline storage tanks.

A new tank terminal was proposed adjacent to a petrochemical Quay in Jubail Industrial City, Saudi Arabia. The tank terminal consisting over 40 number of tanks which are used to provide logistic for chemical handling and storage services for the region.

Our company was invited to prepare a comprehensive environmental impact assessment and assist with the application of required environmental permits. During the EIA study, our team worked with other contractors and successfully implemented many tasks, including fugitive emission inventory development and dispersion modeling, noise modeling, accidental chemical spill modeling , and preparation of environmental emergency response plan. 

Saudi Aramco has proposed to build a desalination plant and a sewage treatment plant of the King Abdullah University of Science and Technology (KAUST) Research Park Utilities Complex. As the location for seawater intake pump station, routing of onshore/offshore pipeline and the location for the intake/outfall mouths have been changed, the EIA previously prepared needs to be updated to address the impacts associated with project modification.

Our company was contacted to update the EIA study through performing the following tasks:

• re-visit the dispersion modeling using the updated design parameters from the Seawater Intake system,
• undertaking dispersion modeling of nearshore discharge for a second shoreline discharge of water from the research park laboratories,
• modeling of the dispersion of sediment plumes produced during dredging activities,
• develop a Construction Environmental Management Plan (CEMP) for the dredging and offshore construction activities associated with the development of the project.

Our Company was invited by Riyadh Municipality in Saudi Arabia as an external reviewer for Flood Protection and Storm Water Drainage Schemes for Azulfi and Al-Ghat Governorates due to our expertise in stormwater management. Our civil engineers and water resource specialists evaluated the proposed flood protection methods and the conceptual design of alternative solutions, based on their professional knowledge and expertise in topography, hydrology, geology and hydraulics.

They provided valuable comments and suggestions on the preliminary design for stormwater drainage network and flood control facilities such as dams, channels, pipes, and artificial ponds. This project review experience also provides us with an excellent perspective of the type of information required to evaluate stormwater drainage design proposals.



Saudi Aramco has proposed to restore a terminal in Yanbu to facilitate crude oil supply to local refineries and fuel oil importation. The project will de-mothball, upgrade and modify all facilities needed to export crude oil from the terminal. Consequently, a  comprehensive environmental impact assessment was required to evaluate the potential environmental impacts and identify mitigative measures. 

Our company was invited to undertake an air dispersion modeling study which comprises obtaining an emissions inventory for potential emission sources at the terminal, performing meteorological modeling, and conducting dispersion modeling tasks. Our team has successfully completed the air modeling study by following technical procedures set out by Saudi Aramco Engineering Procedure and Standards, such as SAEP-340 and SAES-A-102.
