Ground-level ozone is the most common air quality problem in Harris County. Ozone pollution is mainly a daytime problem when temperatures are high, sunshine is strong, and winds are weak. When this occurs, ozone can accumulate to unhealthy levels, especially for people with respiratory conditions who are participating in strenuous outdoor activities.
The school district has developed a plan to respond to high concentrations of ground-level ozone. The district’s plan follows the recommendations from Harris County Office of Homeland Security & Emergency Management and Texas Commission on Environmental Quality.
When the school district receives an ozone alert from Harris County, district personnel carefully monitor the ozone levels in northwest Harris County. When the ground-level ozone reaches unhealthy levels in our geographic area, campuses are notified of the specific ozone warning level of orange, red, or purple. Based on the ozone warning level, certain strenuous outdoor activities, such as physical education or recess, will be curtailed for some or all students.
Following an ozone warning, campuses will implement the following guidelines:
Students in sensitive group will curtail all outdoor activity. The sensitive group includes students with respiratory or heart conditions. Each campus nurse has developed a list of students in this group based on health card information.
All other students will participate as scheduled.
Students in sensitive group will curtail all outdoor activity.
All other students will limit outdoor activity to one hour or less.
If the scheduled outdoor activity is longer than one hour, alternate plans will be implemented by the teacher, coach, or sponsor.
All students will curtail all outdoor activity regardless of duration.
Additional printed information about ground-level ozone is available at the school office or on the district’s website.
