Excel Air Quality Monitoring Dashboard-As of June 30, 2026
Independent Environmental Monitoring Dashboard
Excel Environmental Resources review of the North/West Battery Park City Resiliency Project
BPCA retained Excel Environmental Resources as its independent environmental monitor. Enovate Engineering, the contractor’s monitoring subcontractor, operates the project’s Community Air Monitoring Plan (CAMP) monitoring system. This dashboard translates Excel’s independent findings into plain language and maintains a rolling record as each new monthly report is released.
Latest Month: June 2026 — What Residents Need to Know Now
June also marked the first month in which Excel conducted two field inspections. During the June 5 inspection, Excel observed visible dust in Reach 5 and reported that active mitigation was not being used during one stone-handling operation until Excel raised the issue and water spraying began.
Rolling 6-Month Snapshot
This section will always show the six most recent reporting months using the same resident-facing measures. Excel is BPCA’s independent monitor; Enovate operates the contractor’s CAMP monitoring system. As new Excel reports are released, the cards will update and older months will move to the archive.

Independent Field Oversight
April — Remote Review Only
Excel reported that it was not yet fully onboarded, conducted no onsite inspections, and did not yet have access to noise data.
May — First Site Visit
Excel conducted one site visit on May 15. It did not observe visible dust during the visit, although remote monitoring showed PM events in Reach 1 and Reach 5 that day.
June — Two Site Visits
Excel inspected on June 5 and June 26. On June 5, it observed visible dust in Reach 5 and said additional water spraying began after Excel raised the concern.
What “Independent” Means Here
Excel is primarily overseeing Enovate’s contractor-operated network. Excel’s own direct measurements were limited to periodic field inspections rather than a separate 24/7 independent monitoring network. Excel’s scope also indicates that event causes may be relayed as determined by the BPCA project team, so residents should distinguish independent review from fully independent cause attribution.
Monitoring Integrity & Coverage
Actual Monitor Locations Are Not Always Clear
The reports use a mixture of design and apparent as-built monitoring plans, even though the underlying plans state that monitor locations may be adjusted in the field. A dated, “as-operated” monthly map is not provided.
Reach 5E / Reach 6A North
June acknowledges micropile drilling in Reach 5E, but the inspection narratives do not separately document the Gateway-adjacent work area, reconcile the Reach 5E / Reach 6A North designation, or clearly identify which monitors served that work.
Monitor Outages
Enovate reports multiple monitor power disconnections, but Excel’s reports do not provide a resident-friendly monitor-by-monitor uptime and outage ledger. Future reporting should identify the monitor ID, cause and duration of each outage, whether another monitor provided adequate redundancy, whether the outage affected upwind/downwind site-contribution calculations, and when full monitoring was restored.
Negative Readings
April notes negative rolling-average readings attributed to automatic calibration overcorrection. Excel says they should be treated as zero but does not quantify how often this occurred.
Corrective Actions & Accountability
What the Reports Do Provide
Excel identifies events where stronger mitigation, work stoppage, BMP re-evaluation, or other action should have occurred.
What Is Missing
A resident-friendly corrective-action register: date, issue, required response, who was notified, what was done, when Excel verified it, and whether the item is open or closed.
Were the Reports Layperson-Friendly?
GTA Watch List / Open Questions
Reconcile the Counts
Why do Excel and Enovate report different event totals, especially May?
Document Stop-Work Events
Which Level 2 events actually resulted in work stopping, and when did work resume?
Publish As-Operated Monitor Maps
Show the actual monitor location, ID, installation date, relocation dates, removal date, and outages for each month.
Clarify Reach 5E / 6A North
What work was occurring there during Excel visits, what monitors served it, and what independent readings were taken?
Complete Noise Oversight
When did Excel obtain full noise-monitoring access, and will prior months be reviewed retroactively?
Track Corrective Actions
Future reports should show open/closed status and verification for each significant issue.
Publish Monitor Uptime & Outages
Provide monitor ID, outage cause, duration, redundancy, impact on site-contribution calculations, and restoration time for every material outage.
Definitions & How to Read This Dashboard
This reference section explains the technical shorthand used above. Linked terms throughout the dashboard jump here for readers who want more detail.
Community Air Monitoring Plan (CAMP)
The project's CAMP establishes how construction-related air monitoring is performed and sets short-term response thresholds known as Action Levels. The purpose is to trigger protective action during construction when particulate levels rise.
↑ Back to topPM / Particulate Matter
PM means particulate matter: tiny airborne solid particles and liquid droplets. The dashboard counts short-term PM Action Level events reported by the project monitors; these are not automatically the same thing as violations of longer-term regulatory air-quality standards.
↑ Back to topPM10
PM10 refers to inhalable particles with aerodynamic diameters generally 10 micrometers or smaller. Construction dust can contribute to PM10, which is why the CAMP monitors it separately.
↑ Back to topPM2.5
PM2.5 refers to fine particles with aerodynamic diameters generally 2.5 micrometers or smaller. These particles are smaller than PM10 and are monitored under their own CAMP thresholds.
↑ Back to topAction Level 1
Level 1 is the lower CAMP response threshold. When construction-related particulate levels reach this level, the plan calls for additional or re-evaluated dust-control measures while work may continue only under the applicable CAMP conditions.
↑ Back to topAction Level 2
Level 2 is the higher CAMP response threshold. After required suppression efforts, an applicable Level 2 condition requires work to stop, controls to be re-evaluated, and work to resume only after particulate conditions are reduced below the applicable threshold and visible migration is controlled.
Why GTA highlights it: Level 2 events provide an especially important test of whether the project's required protective response was followed.
↑ Back to topSite Contribution / Upwind & Downwind
The contractor compares upwind and downwind readings to estimate the portion of particulate levels that may be attributable to construction. Wind direction is therefore central to the calculation. When wind is too light to determine a downwind station, the project may be unable to calculate a site-contribution value even though raw monitor readings still exist.
GTA has therefore asked BPCA to explain the siting rationale for each reach and to provide dated, as-operated monitor locations together with wind direction, monitor relocations, outages, and any supplemental or mobile monitoring used when fixed locations do not create a meaningful upwind/downwind comparison.
The dashboard does not characterize west-to-east winds as the prevailing condition for all periods unless supported by the project's own meteorological data. The concern applies specifically during periods when wind direction makes a north–south monitor pair crosswind rather than upwind/downwind.
↑ Back to topExcel Site Inspection
A site inspection is an onsite visit by Excel, BPCA's independent monitor. Excel also reviews the contractor's monitoring data remotely. A site-inspection count therefore should not be read as the number of days environmental monitoring occurred; the contractor-operated monitors run separately.
↑ Back to topNoise Alerts / Noise Review
This dashboard reports noise information only when Excel's monthly reports provide enough information to do so. Excel reported that it did not yet have noise-monitoring access in April and May and was reviewing Enovate noise reports in June. “Not available” does not mean zero noise events.
↑ Back to topPublic Reporting Delay
The reporting-delay figure is the number of days from the end of the reporting month to the date shown on Excel's public monthly report. It measures when residents received the report, not whether Excel communicated particular concerns to the project team in real time.
↑ Back to topWhere Is the Work? Understanding the Project Reaches
The project is divided into numbered construction areas called Reaches. The visual below is more intuitive for community use because it shows the full Battery Park City project alignment and all seven reaches.
Why this matters: environmental-monitoring results, monitor locations, outages, work activities and Excel observations are often reported by Reach rather than by familiar building, park or street name.
- Reach 1 — West Street Crossing / Tribeca
- Reach 2 — North Esplanade
- Reach 3 — Rockefeller Park
- Reach 4 — Belvedere Plaza
- Reach 5 — North Cove
- Reach 6 — South Esplanade
- Reach 7 — South Cove
What the first Excel reports covered: April–June monitoring discussion in Excel’s reports focused mainly on the reaches that were active or producing events during that period, especially Reaches 1, 3, 5, 6 and 7. Even so, this GTA dashboard is intended for the broader Battery Park City community, so it should orient residents to all reaches, including Reach 2 and Reach 4.
Reach 5E / Reach 6A North: the Gateway-adjacent area deserves particular care in interpreting the reports. Excel’s June work summary identifies micropile drilling in Reach 5E, while other project materials and community discussion also refer to the nearby area as Reach 6A North. The dashboard flags this as a monitoring-documentation issue rather than silently treating the names as interchangeable.
Resident-facing recommendation: future independent reports should include a dated “as-operated” map showing the actual location of every active air, noise and vibration monitor, along with installation, relocation, removal and outage dates.
