Environmental verification, remediation of exploratory drilling, and completion of site preparation work for a non-operational mining site.
A complete case study of a non-metallic mining site in Saudi Arabia: from identifying open pits to backfilling, leveling, and issuing a documented completion report
Introduction: Why does a non-operational site need environmental verification?
Sites Non-metallic mining It is one of the industrial sites that leaves a clear environmental impact after operations cease, especially when it leaves Open exploratory pits Piles of excavated material and unsecured dirt tracks. In this study, we review the team's experience. The environmental dimension of environmental consulting In procedure Environmental verification of the current situation For a non-operational site, then follow up on implementation Backfilling and leveling works And issue Completion Report Documented with field evidence.
This work comes in a context of growing interest inAddressing mining-affected sites In Saudi Arabia, specifically with the growing demands Mining licenses Which requires the preparation of environmental settlement and rehabilitation plans that comply with environmental sustainability standards.
Main objective: Transforming the results of status verification into documentable closure actions reduces environmental and operational risks and supports the site's regulatory path.

Project background
The assignment to document began Current environmental and operational status For a non-operational site, as the preview showed Open exploratory drilling Excavation debris and earthworks. Following the issuance of the initial report, the work extended to documenting the implementation of the required treatment through Filling the holes Settlement of affected areas and verification of site condition after completion.
The case study was built on two interconnected phases:
- Defining the baseline and apparent risks: Monitoring the actual condition of the site and documenting environmental observations.
- Follow up on closing the comments: Carry out the backfilling and leveling works and issue a completion report accompanied by field photos.
The first challenge was Separating the effects of previous works The inspection revealed evidence of actual operation. The site showed open pits, piles of excavated material, and earthworks; however, these features alone are not sufficient to prove ongoing operational activity. It was necessary to look for direct operating indicators, such as operating equipment, production-related vehicle movement, loading or screening areas, and emissions or operating noise.
The second challenge was Risk assessment based solely on visual evidenceThe third challenge was to formulate recommendations that were appropriate to the situation: protecting the soil and public safety, preventing the spread of the impact, and supporting the regulatory process.
Scope of work of Environmental Dimension Company
- Review the regulatory requirement and available technical documentation to determine the purpose and scope of the verification.
- to implement Field visit A systematic visual inspection of the general condition of the site and the surrounding environment.
- Checking for the presence or absence of operational work and indicators of direct activity at the time of inspection.
- Monitoring pits, piles of material, tracks, debris, and any visible signs of emissions or leaks.
- Assessing aspects related to soil, dust, noise, debris, vegetation cover, and safety.
- Classifying the level of observations made and formulating actionable procedures and recommendations.
- Preparing Technical Report Regarding the current situation, while maintaining documentation evidence in the project's internal records.
Implementation Methodology: From Desk Review to Field Inspection
1. Desk review and setting verification limits
The team began by reviewing the organizational purpose of the assignment and the available information about the nature of the activity and the site's condition. This review was used to define the screening questions: Are there any operational works taking place at the time of the visit? What physical impacts are present? Are there any visible sources of pollution? What measures are necessary before resuming or commencing any work?
2. Field surveys based on specific indicators
A field tour was conducted that included the site area and its immediate surroundings. The visit was not limited to taking general photographs; rather, operational indicators, ground surface condition, excavations and piles of material, paths, debris, sources of noise and dust, vegetation cover, and visible sensitive receptors were examined.
3. Cross-checking and risk assessment
Field observations were compared to the verification range defined at the start of the work. A distinction was made between the absence of an apparent indicator and proof of the absence of contamination. the risks were then assessed according to the probability of occurrence and the severity of the impact, with priority given to open pits, potential dust, and debris accumulation.
Key environmental observations
The evidence was based on an examination of the basic condition, photos of the backfilling and leveling being carried out with the appropriate equipment, and then photos of the verification after completion.
| Environmental element | Technical Note | Significance |
|---|---|---|
| operational status | No operating equipment or production-related operational activity was observed at the time of inspection. | The site is not operational at the time of visit. |
| Previous effects | The presence of open pits, piles of materials, and dirt tracks resulting from previous interventions. | It needs proper adjustment, documentation, and processing. |
| Soil and Earth's Surface | Exposed surface and loose materials that are susceptible to agitation and erosion. | Possibility of dust blowing and localized surface deterioration. |
| air and dust | There are no visible operational emissions, with the site susceptible to dust being stirred up by wind or vehicle movement. | The need for controls when resuming business. |
| Noise: | No apparent operational noise sources were detected. | This corresponds to the absence of operation during the visit. |
| Waste | A limited amount of debris was detected in one of the depressions. | Systematic removal and documentation of the procedure are required. |
| Vegetation | Limited and scattered desert cover without density or sensitive habitats apparent within the scope of the examination. | Avoid unnecessary removal. |
| Environmental safety | Unsecured excavations may cause falls, collapse of sides, or accumulation of debris. | Low to moderate risks that require control. |
Treatment, backfilling and leveling works
Implementation began by identifying locations Exploratory drilling Within the scope of the treatment and field review of its condition. Then leveling equipment was used forFilling the holes The low-lying areas were filled in, utilizing the excavated soil itself and avoiding the use of waste or contaminating materials in the backfilling. The ground surface was then leveled to eliminate differences in elevation and improve site evenness.
The treatment included edges and unsafe areas, and cleaning the work area after implementation. It was applied during the work. Environmental and operational controls Should include:
- Minimize dust generation as much as possible.
- Dumping waste into pits is prohibited.
- Avoid creating additional pits or deformities.
- Inspect the stomach to prevent leakage of fuel or oil.
- Restricting access to work areas and using appropriate protective equipment.

Technical lessons learned
The project demonstrated the importance Converting status verification results into verifiable closure proceduresOpen pits were not recorded as merely a descriptive observation; rather, they were linked to executive steps that included identification, backfilling, leveling, and verification after completion.
The experience also confirmed the necessity of:
- precise distinction between Previous effects And the actual operational activity.
- Documenting each stageAnonymous images And a precise technical description.
- Use Suitable backfill materials Avoid introducing new pollutants.
- Preparing Completion Report It serves as proof before regulatory authorities.
Frequently Asked Questions about Environmental Verification and Mining Site Remediation
What are the steps for environmental verification of a non-operational mining site?
Environmental verification steps include: desk review of documents, field inspection to monitor open pits and waste, environmental and safety risk assessment, and then preparation of a technical report documented with photographs that includes remediation recommendations and lockdown measures
How are exploratory drilling operations handled at mining sites?
Exploratory drilling is handled by identifying its location in the field, then using leveling equipment to backfill it with suitable soil (preferably the drilling output itself), then the surface is leveled to eliminate differences in elevation and improve evenness, while applying safety and environmental controls during implementation.
What is the importance of the environmental compliance report?
The Completion of Settlement Report is a regulatory proof document that confirms the implementation of the required treatment, documents the condition before and after the procedure, supports the environmental compliance path before regulatory authorities, and reduces legal and operational risks.
What are the environmental risks of open pit mining at non-operational mining sites?
The risks include: rainwater accumulating and creating an insect breeding ground, collapse of excavation sides, risks of falling and tripping, excavations becoming collection points for debris, and dust being stirred up from loose materials.
